Monazite-(Ce) with Quartz Arsenopyrite Only a very small percentage

Only a very small percentage of the Augelites from Machacamarca are found in twinned crystals

The second significant attribute of these specimens is the fact that they formed on a solid Quartz-Diorite porphyry matrix

so it's mostly a reference specimen

Monazite is usually found in granitic pegmatites

Monazite-(Ce) with Quartz Arsenopyrite Only a very small percentageMonazite gets its name from the Greek word "monazein", which means "to be alone", in allusion to its isolated crystals and their rarity when first found. Monazite is usually found in granitic pegmatites, but these crystals are found in hydrothermal tin veins where there is an absolute absence of Thorium (usually a trace element in Monazite). This is a remarkable, very well crystallized, ridiculously rare, specimen consisting of sharp, lustrous,
