Which rock is more susceptible to chemical weathering in humid environment, granite or gabbro ? |
|
Answer» Answer: If there is more quartz present, the rock must be named quartz gabbro. If quartz makes up more than 20%, then the rock is one of granitoids. Granite is a medium-to coarse- grained ACID igneous rock with essential quartz (>20%) and feldspar, where ALKALI feldspar constitutes between 100 and 35% of the feldspars, and MINOR mafic MINERALS. |
