Geologists in some underground gold mines collect grab samples from broken ore as a method of grade control It is often known as muck or broken rock sampling Generally the goal of grab sampling is to try and reconcile the mined grade at the ore source to the predicted head grade Additionally the samples may be used to verify prior in situ estimates of grade such as those derived from face Tephra are igneous rocks blown into the air during a volcanic eruption Lava is molten rock that flows out of a volcano during an eruption Lava is the term used to describe igneous rocks
