High River Gold Closing in on its Initial Goal of a 1 Million Ounce Resource at the Bissa Project in Burkina Faso Simple flaked lithic industries on cryptocrystalline raw materials, without pottery, were also found in an upper terrace of Bukit Pantaraan directly above the Neolithic location just discussed , and also in the Neolithic layers themselves at Pantaraan 1, although in this case there is a strong possibility that they eroded from the upper terrace during the Neolithic occupation. Neolithic foundations in the Karama valley, West Sulawesi, Indonesia No regional zoning of zeolite assemblages was apparent in this study Figure 8 shows that the zoning sequence and textural evidence suggest the following crystallisation sequence: Natural zeolites filling amygdales and veins in basalts from the British Tertiary Igneous Province on the Isle of Skye, Scotland AMC’s vision and focus during the past 15 years has been to value add to the world’s largest source of cryptocrystalline magnesite at Kunwarara near Rockhampton in Central Queensland through a range of successful magnesia product applications, processes and research projects. Glacial cycles and Palaeolithic adaptive variability on China’s Western Loess Plateau Thus the gap is almost unrecognizable in the Ikla and Staicele cores, where the nodular wackestones of the Rumba Formation lie upon the cryptocrystalline micritic limestones of the Staicele Member of the uppermost Saarde Formation.

Now, new archaeological evidence is getting the same scrutiny by scientists Early human hunters had fewer meat-sharing rituals August 13, A University of Arizona anthropologist has discovered that humans living at a Paleolithic cave site in central Israel between , and , years ago were as successful at big-game hunting as were later stone-age hunters Ancient bone find may change Filipino history August 3, Archaeologists have found a foot bone that could prove the Philippines was first settled by humans 67, years ago, thousands of years earlier than previously thought, the National Museum said Tuesday.

Scientists find genetic evidence for southern origin of modern humans in East Asia July 27, Genetic studies have provided evidence for an African origin of East Asian populations, but their prehistoric migration routes in the Asia region remain a long-standing controversy. On the basis of the genetic evidence generated

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.. The method was developed in the late s by Willard Libby, who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon (

Vedas and Motion of Planets The core foundation of Hindu belief is that Vedas contain source of all knowledge — physical or metaphysical. However in last odd years, this belief has come under scrutiny due to the advances that modern science claims to make. However in modern era of religious marketing, another group has come up which would go to any length to discover scientific errors in Vedas. This is the group which would want million Hindus to lose faith in Vedas and their religion and embrace what they believe is the final message of God.

Yes I am referring to Islamic and Christian evangelists. This is because a bulk of Islamic evangelists believe that Jesus will come again towards end of the world after which they would reach Paradise forever.

In lieu of an abstract, here is a brief excerpt of the content: Archaeological Researches on the Excavated Finds at the Ancient City of Wadee Myo Nyunt Aung bio One of the most exciting recent discoveries in the archaeologically rich terrain of Myanmar has been the resurrection of a hitherto unfamiliar ancient site of human habitation—Wadee. It is about 8 kilometers to the southeast of Nahtogyi and 3.

Circa (from Latin, meaning ‘around, about’) – frequently abbreviated c., ca., or ca (and less frequently circ. or cca.) – signifies “approximately” in several European languages (and as a loanword in English), usually in reference to a date. Circa is widely used in historical writing when the dates of events are not accurately known.. When used in date ranges, circa is applied before each.

It was the high-resolution reexamination of pollen stratigraphy, the identification of plant macrofossils, and the new technique of accelerator mass spectrometry 14C dating of these macrofossils that enabled documentation of the event in the southern New England region of the United States Peteet et al. In the central Appalachians, a warm, wet interval coincident with the Younger Dryas event suggests a sharp climatic gradient that might have forced the northward movement of storm-track moisture Kneller and Peteet, l The documentation of the Younger Dryas event over much of North America demonstrated that it was not limited to the circum-Atlantic region Peteet et al.

Central America and the Caribbean Marine evidence of the Younger Dryas event is recorded as an interval of increased upwelling or decreased riverine runoff from adjacent South American land in a core from the Cariaco Basin in the Caribbean Hughen et al. Terrestrial evidence is primarily from three sites Leyden, Evidence indicates a temperature decline of 1. The National Academies Press.

Challenges to Biblical Credibility. Gone are the romantic images of gentlemen in pith helmets carting off treasures to the museums and estates of Europe. Gone, too, is the idea that archaeologists are always on the side of the Bible believer. Modern interpretations frequently challenge biblical accounts. Further, dates generated by new techniques are often at odds with the timing of events given by Scripture.

The purpose of this first article is to discuss problems with radiocarbon and tree-ring dating or dendrochronology , which are the two most common direct dating techniques in archaeology.

The core foundation of Hindu belief is that Vedas contain source of all knowledge – physical or metaphysical. However in last odd years, this belief has come under scrutiny due to the advances that modern science claims to make.

The similarity of Chinese-Olmec mythology and symbolism has been the subject of scholarly debate for over one hundred years. It is perhaps no coincidence that the Olmec culture appears around BC during the beginning of the Shang Dynasty, and the first written history of China begins. It was the start of the Bronze Age resulting in ornate bronze works of art, bronze chariots and weaponry. The first Chinese script appears at this time along with extensive irrigation systems and other public works projects, all indicators of a sophisticated and advanced culture.

It was also a time in Chinese culture when Jade was more valuable than gold, and likewise with the Olmec elite who had Jade deposits located in now Honduras and Guatemala. It may not be coincidental the Olmec, during their Middle Formative period BC , mastered the difficulties of shaping and drilling Jade a stone so hard that it cannot be worked with steel tools , with abrasive materials into small ornamental and votive pieces.

The last stage of incision by the river is thought to be driven by the Milankovitch eccentricity cycle. When rivers flood , sediment deposits in sheets across the floodplain and build up over time. Later, during a time of river erosion, this sediment is cut into, or incised , by the river and flushed downstream. The previous floodplain is therefore abandoned and becomes a river terrace.

A river terrace is composed of an abandoned surface, or tread, and the incised surface, or riser. Age of terraces[ edit ] Time of incision versus time of aggradation[ edit ] The ages of incision and flooding aggradation can have different interpretations for each fluvial system, where each region may respond independently to external variation.

Simple and linear models to explain the origin and dispersals of Homo sapiens seem to be progressively outdated by the new fossil, demographic and genetic evidence. Homo sapiens in the Eastern Asian Late Pleistocene. María Martinón-Torres, Xiujie Wu, José María Pei, J. Thermoluminescence dating of the Peking Man site and other.

Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the “radiocarbon age”, which is the age in “radiocarbon years” of the sample: Radiocarbon ages are still calculated using this half-life, and are known as “Conventional Radiocarbon Age”.

Since the calibration curve IntCal also reports past atmospheric 14 C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age. When a date is quoted, the reader should be aware that if it is an uncalibrated date a term used for dates given in radiocarbon years it may differ substantially from the best estimate of the actual calendar date, both because it uses the wrong value for the half-life of 14 C, and because no correction calibration has been applied for the historical variation of 14 C in the atmosphere over time.

The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the 14 C generated by cosmic rays to fully mix with them. This affects the ratio of 14 C to 12 C in the different reservoirs, and hence the radiocarbon ages of samples that originated in each reservoir.
