Olivine would weather faster than quartz
Quartz and olivine have different crystallization temperatures, with olivine forming at higher temperatures than quartz. This means that in most cases, olivine and quartz are not typically found together in the same igneous rock as they would have crystallized at different stages in the cooling process. Olivine is a common mineral in mafic rocks (rich in magnesium and iron) while quartz is more common in felsic rocks (rich in silica).
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
feldspars. feldspars.
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
A non-metallic mineral such as quartz or calcite.

They would include olivine, quartz, the feldspars, and the micas.

Chalk would weather fastest, followed by limestone.
feldspars. feldspars.
This would be quartz.
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
They would weather slower than on earth due to different amts of wind and rain than on earth.
Quartz
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
There are many sorts of igneous rocks. Granite is made of quarts, feldspar, and mica, while basalts are made of less than 20% quartz and less than 10% feldspar and the rest made up of pyroxenes and olivine.
Quartz because its harder than calcite and the quartz in thicker.
