Answer :
Answer: HARD TO KNOW, BUT I WOULD SAY NO.
Explanation: Talking about minerals, I seriously. Just take about the core of the Earth and the subyacent layers. The conditions down there are EXTREME, it´s barely impossible that minerals behave the same way as up here.
Hardness, composition, reaction to high or low temperatures. I mean, do you even imagine if there´s a rock that can resist the temperature of the sun? or a mineral whose temperature is lower than the ABSOLUTE ZERO. So not. I´m almost sure that there´s not a way of assuring that we know all the existing mineral or elements.
