The answer is yes. Indeed, low sulphur basalt is probably better than feldspar or quartz because of the broad spectrum minerals, trace elements and metals present.
Up to 70 elements from the Periodic Table can be seen via MS ICP analysis.
Cation exchange will be dramatically enhanced and holding capacity for water will double or triple.
However, there are many types of basaltic material and it is important to check the levels of arsenic, Mercury, lead, and sulphur particularly. There is a site, www.remin.com, which details uses and results for a type of basalt that has been tested on large scale growing ranches in California and Arizona. Or you could email them at reminworld@yahoo.com.
It is the large broad spectrum spread of nutrients available from certain basalt materials that make them much more beneficial for remineralization of the soil.
On the Mohs Scale of mineral hardness, feldspar is 6 and quartz is 7, so quartz is harder. What does this mean? quartz will scratch feldspar, but feldspar will not scratch quartz.
There is no mineral that would satisfy the question. If a mineral is able to scratch feldspar, it would have a Mohs hardness of 6 or above. Fluorite is rated as a 4. It would be impossible for a mineral which scratches feldspar to be unable to scratch fluorite.

The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.

Quartz and feldspar are commonly found together in granite and gneiss.

Igneous rocks are composed mainly of silicate minerals. Granite is mostly quartz, feldspar and mica. Basalt is mainly feldspar, pyroxine and amphibole. Diorite can be a mixture of all of these minerals. Peridotite is mainly olivine (peridot) and pyroxine.
Basalt scores an 8 on the Moh's scale. This makes it harder than quartz and vanadium, but weaker than boron and titanium carbide. It can easily scratch steel and glass. It is just about as hard as topaz. Basalt is also an igneous rock, formed by hardened lava, which explains why it is so hard.
