Diamond is number 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Moh's scale. It also has the most dense atom ical configuration of any mineral, and is transparent over the greatest number of wavelengths.ISTINGUISHING SIMILAR MINERALS. The only mineral that can possibly be be confused with Diamond is waterworn Quartz pebbles which may resemble waterworn Diamonds, but the hardness and luster of Diamond will easily differentiate the two.
.A disconformity is an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.
Basically both indicate a break in deposition, either by nondeposition or erosion. An unconformity describes this phenomena (break in the rock record: hiatus). There are several types of unconformities and of course each has a specific name (eg. nonconformity, disconformity, angular unconformity).A disconformity discribes an unconformity at which the same general layering is present above and below the disconformity.here are several types of unconformities and of course each has a specific name (eg. nonconformity, disconformity, angular unconformity).
