Which of these minerals is not considered a silicate? A. Calcite B. Olivine C. Plagioclase D. Muscovite
In this assignment, you will identify some minerals. The
ability to identify minerals is one of the most fundamental
geological skills. It is an essential skill in identifying rocks,
for one must first identify the minerals within a rock before the
rock itself can be identified. Only after minerals and rocks have
been identified can their origin, classification, and alteration be
adequately understood. The ability for a geologist to identify
minerals by using the simplest tools is often a necessity,...
Soil is a complex mixture of minerals, organic matter, air and water in which percentages? The two main types of chemical weathering are Select one: oa. Oxidation and reduction. Ob. Hydrolysis and oxidation. c. Hydrolysis and dissolution. O d. Alteration and oxidation. When quartz weathers it produces the following products: Select one: a. Silica grains. b. Calcium and serpentine ions. c. Clay minerals and sodium ions. d. Carbonate and silica grains. Soil is a complex mixture of minerals, organic matter,...
2. The chemical formula for biotite is K2Mg2ASİ,01 (OH) 2 Calculate the coordinator number for K. Using the table identify the positions of the K number of O ions surrounding the K ion? and O ions. Does your predicted value agree with the r minerals in the earth's crust are the silicate minerals. The basic building block for the silicate minerals is the silica tetrahedron. The tetrahedrons can be arranged in different ways to create the various classes of silicate...

What properties cause some magmas to be more felsic than others?Different minerals crystallize at different temperatures, changing the chemistry.Some parts of the mantle are felsic and some are mafic, creating felsic magma in the crust.Water from subducting ocean plate mixes with the magma to create felsic magmaAnimals change the chemistry of the magma, making it more felsic.Silica content in igneous rocks controls (select the correct term)["texture", "viscosity", "crystal size"] which, in turn, controls ["eruption style", "crystal size"] ...
