Experimental petrology it is possible to examine the behavior of a magma body as it slowly cools and crystallizes over time Experimental petrology Experimental petrology is the field of research concerned with experimentally determining the physical and chemical behaviour of rocks and their constituents. Because there is no way to directly observe or measure deep earth processes, geochemists rely on experimental petrology to establish quantitative values and relationships in order to construct models of the deep earth. Experimental petrology can range from creating artificial magmas to measure crystallization behavior to observing recrystallization of minerals at varying P/T (Pressure/Temperature) conditions. Although methodology varies
Institute for the Study of Human Knowledge web site for a project entitled "The Human Journey". It aims to "follow humanity from our origins in Eastern Africa and the Middle East to the present day, with an eye to what comes next." Institute for the Study of Human Knowledge The Institute for the Study of Human Knowledge (ISHK) is a non-profit educational charity and publisher established in 1969 by the noted and award-winning psychologist and writer Robert E.
