How would the color of the diorite change if it contained less hornblende and more feldspar?
If diorite contained less hornblende and more feldspar, its color would likely lighten and become more pale or grey, as feldspar is generally lighter in color compared to hornblende. The reduced presence of hornblende would diminish the dark tones, while the increased feldspar would add lighter hues, resulting in an overall lighter appearance for the diorite.

How does metamorphism affect baslt?
Basalt when metamorphosed turns to the following rocks: (LEAST PRESSURE AND TEMPERATURE TO THE MOST) + mineralogy -Greenschist-albite, epidote, chlorite -Amphibolite-amphioble, plagioclase feldspar -Granulite-calcium-rich pyroxene and plagioclase feldspar -Eclogite-sodium-rich pyroxene and garnet
Is the change from feldspar to clay minerals an example of chemical weathering?
It depends on the type of feldspar you're wondering about. I'm only 100% sure on one K-spar (Orthoclase) and one end-member of Plagioclase. Orthoclase (and probably the other K-feldspars as well - Microcline and Sanidine) weather to Illite, the most stable of the clay minerals: Orthoclase + CO2 + H2O ---> Illite + [K+ + HCO3- + SiO2]aq Albite (the Na-end-member of the plagioclase solid solution (Anorthite is the Ca-end-member, which may well weather in the same manner) weathers to Kaolinite: Albite + CO2 + H2O ---> Kaolinite + [Na+ + HCO3- + SiO2]aq
What geologic process change granite igneous rock into gneiss metamorphic rock?
Granite can be changed into gneiss through the process of metamorphism, where heat and pressure alter the mineral structure of the rock. This process causes the minerals in the granite to recrystallize, forming distinct banding and foliation characteristic of gneiss. The original minerals in the granite are reorganized into new minerals such as mica, quartz, and feldspar, giving gneiss its unique appearance.
Why does granite not change in the same way as limestone?
Granite and limestone are very different rocks. Granite is an igneous rock formed from magma. It contains many different types of minerals.
Compare the ways in which ironmagnesium minerals and feldspars crystallize from magma?
In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types. When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core. For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.
Is mutation a change in the genetic information contained in a gene?
true
What kinds of rocks can be change into metamorphic rocks?
Many kinds of rocks both of igneous and sedimentary nature eg; Limestone (sedimentary ) to marble or granite or diorite (igneous) to gneiss.
Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
How do you change the low beam on a 2003 Hyundai Accent hatchback?

What would happen if you rubbed a piece of fluorite a piece of feldspar?
If you rubbed a piece of fluorite against a piece of feldspar, neither mineral would really change. Both minerals are relatively hard and have different chemical compositions, so they would not interact in a way that would result in a noticeable reaction.

How do you change a clause in a HOA covenant?
Each document details the process to amend or change or modify it. Best practices dictate that you work with an attorney to change any covenant contained in the association's governing documents.
Is the pressure of contained neon gas increases as more gas is added to the container a chemical change?
No, the increase in pressure of contained neon gas as more gas is added to the container is a physical change, not a chemical change. This change is due to the gas particles colliding more frequently with the walls of the container, resulting in an increase in pressure without any new substances being formed.
