White and Hamilton (J World Prehist 22: 357–97, 2009) have proposed a model for the origin of the Southeast Asian Bronze Age founded on seven AMS radiocarbon determinations from the Northeast Thai site of Ban Chiang, which would date the initial Bronze Age there to about 2000 BC. Since ...
What is the origin of the oxygen we breathe, the hydrogen and oxygen (in form of water H2O) in rivers and oceans, the carbon in all organic compounds, the silicon in electronic hardware, the calcium in our bones, the iron in steel, silver and gold in jewels, the rare earths utilized,...
SHRIMP U–Pb zircon age, geochemical and Sm–Nd isotopic data are reported for mid-Neoproterozoic volcanic rocks and mafic intrusions in northern Guangxi (Guibei) and western Hunan (Xiangxi) Provinces along the southern margin of the Yangtze Block. The mafic igneous rocks studied are generally syn...
On Earth, the most numerous, largest and longest explorable caves have a karstic origin, mainly due to dissolutions in carbonate or evaporitic rocks (e.g. De Waele and Gutierrez, 2022). But there is also a wide range of caves developing in other rocks (lavas, pyroclastics, sandstones, ...
