It is important that the medical profession plays a significant role in critically evaluating use of diagnostic procedures and therapies as they are introduced tested detection, management, or prevention disease states. Rigorous expert analysis available data documenting absolute relative benefits risks those can produce helpful guidelines improve effectiveness care, optimize patient outcomes, favorably affect overall cost care by focusing resources on most effective strategies.

ABSTRACT: Most granitic batholiths contain plutons which are composed of low-variance mineral assemblages amenable to quantification the P – conditions that characterise emplacement. Some thermometers, such as those based on two feldspars or Fe–Ti oxides, commonly undergo subsolidus re-equilibration. Others more robust, including hornblende–plagioclase, hornblende–clinopyroxene, pyroxene–ilmenite, pyroxene–biotite, garnet–hornblende, muscovite-biotite and garnet–biotite. The quality their...
In this study, structures in plutons and host rocks are coupled with geochronology to track paleodeformation fields from the late Paleozoic Late Cretaceous central Sierra Nevada. Regional NW-striking host-rock foliation, NE- or SW-vergent thrust faults, associated folds developed early Mesozoic Early Cretaceous. Dextral transpressional shear zones Strikes of steep-dipping magmatic foliations temporally vary approximately NW (Triassic–Jurassic) WNW (Late Cretaceous), displaying a progressive...

The transition from late-orogenic to post-orogenic magmatism following major orogenic episodes such as the Neoproterozoic Cambrian East African Orogen (EAO) is an important, yet not well-understood geological event marking cessation of subduction-controlled between buoyant lithospheric fragments. Forming northern part EAO in Arabian-Nubian Shield are three granitic suites that successively intruded same northeastern area and post-date ~640 Ma episode: (1) 620–600 alkali feldspar...
Oxygen isotope compositions of epidote and quartz from chloritic breccias that underlie the detachment fault in metamorphic core complex Whipple Mountains yielded quartz-epidote fractionations range 4.1 to 6.4 per mil increase systematically toward fault. These give mean temperatures decrease approximately 432 degrees C at 50 meters below 350 12 This extreme thermal gradient 82 over 38 (2160 kilometer) is best explained by advective heat extraction means circulating surface-derived fluids....

Construction durations of magma reservoirs are commonly inferred from U–Pb zircon geochronology using various statistical methods to interpret age spectra (e.g. weighted mean ages concordant populations). However, in compositionally different magmas, saturation and crystallization predicted occur at times relative other mineral phases the geological event interest; for instance, emplacement. The timescales these processes can be by numerical modeling measured thermal ionization mass...
