Petrology (from Ancient Greek πέτρος (pétros) 'rock' and -λογία 'study of') is the branch of geology that studies rocks, their mineralogy, composition, texture, structure and the conditions under which they form. [1]
Experimental petrology is the field of research concerned with experimentally determining the physical and chemical behavior of rocks and their constituents. [1] 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.
Petrogenetic grid for metapelites (click to zoom). [1] [2] Each line represents a metamorphic reaction.Metamorphic facies included are: BS = Blueschist facies, EC = Eclogite facies, PP = Prehnite-Pumpellyite facies, GS = Greenschist facies, EA = Epidote-Amphibolite facies, AM = Amphibolite facies, GRA = Granulite facies, UHT = Ultra-High Temperature facies, HAE = Hornfels-Albite-Epidote facies ...
Microlites are minute crystals in an amorphous matrix. In igneous petrology, the term microlitic is used to describe vitric (glassy, non-crystalline, amorphous) matrix containing microscopic crystals. [1]
Ceramic petrography (or ceramic petrology) is a laboratory-based scientific archaeological technique that examines the mineralogical and microstructural composition of ceramics and other inorganic materials under the polarised light microscope in order to interpret aspects of the provenance and technology of artefacts.
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
Definition [ edit ] The Oxford English Dictionary defines psychologism as: "The view or doctrine that a theory of psychology or ideas forms the basis of an account of metaphysics, epistemology, or meaning; (sometimes) spec. the explanation or derivation of mathematical or logical laws in terms of psychological facts."
Health psychology is a discipline that understands the psychological, behavioral, and cultural aspects that affect the physical health and illnesses within individuals. A psychologists with the focus of health psychology would have a biopsychosocial model approach with patients.
