What are the most common types of Archean rocks and how are they thought to have formed? Explain why the presence of white drawf stars helps to indicate the age of clusters. Why is the capture hypothesis not the best hypothesis for the formation of th...
Clay minerals are very common in fine grained sedimentary rocks such as shale, mudstone and siltstone and in fine grained metamorphic slate and phyllite. JazzRoc says: January 9, 2010 at 1:41 pm Ian Bryant: Haha, you contrail people crack me up. Yes, we’re a funny lot, aren’t ...
Because organic acids concentrate at temperatures of 80–120 °C, most organic acids are assumed to be released from the source rocks to the reservoirs in the depth interval of 1500–4000 m. From 1500–4000 m, the sandstone porosities generally decrease from 35% to 15% and the mudstone ...
1. Native soils, formed from the disintegration of the bed- rocks of the country, 2. Drift soils of the uplands. 3. Black soils of swampy areas. 4. Alluvial of the river bottoms. The native soils are not widespread, but are confined, for the most part, to the slopes bordering the ...
