Chemical weathering on the Carnmenellis granite
The behaviour of 25 major and trace elements, together with mineral changes, has been examined in a deep weathering profile on the Cammenellis granite, Cornwall. The bulk chemical and mineralogical composition of the regolith shows only minor changes from the parent rock indicating a low degree of chemical weathering. However, within the regolith marked differences occur between the fine fracti...
متن کاملWeathering of Stone Mountain Granite
The weathering of Stone Mountain Granite (adamellitc) forms kaolinite, endcllite, allophane and gibbsite of which kaolinite is the most stable. Bulk density ranges from 2.65 in fresh rock to a minimum of 1.48 in saprolite. It is a good index of weathering. Abrasion pH ranges from 5.0 in saprolite to 9.3 in fresh rock, and is direct]y related to bulk density and the amount of clay mineral. Among...
متن کاملCharacteristics of acoustic emission during single diamond scratching of granite
The acoustic emission (AE) measured during single diamond scratching of granite can provide valuable information about the structural composition and sawability of natural stone material. As described by Prof. Dr.-Ing. R. Clausen*, Dr, C.Y. Wang** and Dr,-Ing, M. Meding***, scratching tests are shown to i ndicate a direct relationship between the characteristics of AE generated by scoring, the ...

15 صفحه اولExperimental and Computational Study on Hydrodynamic of a Downscaled Mini Vessel USP Dissolution Test Apparatus II
Although not listed on the United States Pharmacopeia (USP), like standard USP 2, small volume USP 2 dissolution apparatus has gained a great deal of attention, especially for cases where small amount of drug product is available for testing in research and design step or evaluations are to be made on a tablet containing trace amounts of the active pharmaceutical ingredient. In this work, first...
