Two of the most common uses of melt inclusions are to study the compositions of magmas present early in the history of specific magma systems. Dendrochronology or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings. Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous. As a result, xenoliths are older than the rock which contains them Absolute Dating Also known as chronometric dating, absolute dating is a more recent advance than relative dating. Examples The Pleistocene time is one event, marked by the appearance of the mammoth and mastodon, wild horses, woolly rhinoceros and saber-tooth cats; also by the Ice Age.
