· Thus, zircon sampling sites are seldom, if ever, selected randomly. Typically, geologists gather zircon grains by using two techniques – convenience sampling and cluster sampling. Zircon samples are collected at the convenience of each research team, who pre-determine where to travel to collect the samples, which are then taken as cluster ...
