The Chemical Index of Alteration (CIA) is a good measure of the degree of chemical weathering. High CIA values reflect the removal of labile cations, such as Ca 2+, Na 2+, and K + in relation to more stable cations, such as Al 3+ and Ti 4+, from the rock during chemical weathering. Conversely, low CIA values suggest low weathering effects …

According to the basalt spectral signature, the spectral behavior of ASTER bands, and the initial ground surveyed data, the basalt extraction index (BEI) is proposed as follows: B E I = B 3 B 4-B 5-B 6-B 8. The obtained results of applying the BEI show that the outcome image specifies the initial basalt identifying points.

Schist: Characterized by its sheet-like structure and formed typically from mudstone or shale. Its platy minerals are larger than those in slate. Gneiss: Has a banded or foliated appearance, usually formed from high-grade metamorphism of igneous rocks like granite. Marble: Marble forms from limestone or dolomite.

Based on the spatial relationship among the basalt prospective area, field basalt points, and basalt layers on the geological map, the high-value areas were roughly divided into five classes, which were marked by numbers in the red box of Fig. 12 (a). Class 1 is comprised of overlapping area with basalt points and basalt layers.

Basalt is an extrusive igneous rock composed primarily of plagioclase feldspar and large amounts of mafic minerals like pyroxene. It has an aphanitic texture, meaning its interlocking crystals cannot be seen by the naked eye. It is usually dark gray, black, or dark greenish, and is often vesicular or porphyritic.

Abstract：Emeishan basalt is a typical medium with low permeability. The weathering of basalt rock mass results from basalt block weathering. The weathered basalt block has a shell-like structure formed by core stone which is surrounded by one or more layers of saprolite crusts. From the block surface inward, the nearer it approaches …

August 17, 2023 by Mcnair, B. Basalt is a hard, fine-grained, dark-colored volcanic or extrusive rock. It has primarily calcium-rich plagioclase and augite. Also, it may have minor amounts of other minerals like quartz, olivine, foids, alkali feldspar, biotite, and amphibole. This rock is undoubtedly popular, only rivaled by granite.
