Experimental petrology 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 from experiment to experiment, in general the procedure involves evaluating a synthetic rock or magma (created from a blend
The Gothenburg Study of Children with DAMP The Gothenburg Study of Children with DAMP The Gothenburg Study of Children with DAMP was a study of six-year-old children in Gothenburg, Sweden that began in 1977. The purpose was to find out what proportion of the children had Deficits in Attention, Motor control and Perception (DAMP), formerly known as Minimal Brain Disorder (MBD), and to follow the development of that group over the years. The results and discussions have been published in four dissertations and approximately 30 scientific papers. The first phase of the study was designed mainly by Christopher Gillberg and Peder Rasmussen. Initially, preschool teachers in all
