At the Kakkonb geothermal area, Japan, a large Quaternary granitic body is dstributed below ca 2.5 km ckpth from the surface, associating with thick high-temperature contact me&amorphic zones in the overlying formations, and a meteoric-water-cbminated type hydrothermal system is developedat present time. During the 'Deep-seated Geothermal Resources Survey', WD-la well was drilled to 3729 m dept...

Introduction: The age significance of isotope chronometers in basaltic shergottites is not agreed yet [1-3]. Bouvier et al. [3] argued that crystallization ages of shergottites were old (~4.1 Ga), and suggested that young ages of shergottites (i.e., ~180 Ma) represent reset by shock metamorphism. Baddeleyite (ZrO 2) is an important mineral for U-Pb dating of basaltic shergottites. By compressio...

The Puncoviscana Formation, largely cropping out in NW Argentina, is mainly composed of a pelite-greywacke turbidite sequence affected by incipient regional metamorphism and polyphase deformation. Metapelites, composed mainly of quartz, albite, dioctahedral mica and chlorite, were sampled in the Lules-Puncoviscana and Choromoro belts. Lattice-fringe images, selected area electron diffraction an...

Malware detection is a crucial aspect of software security. Malware typically recur to a variety of disguise and concealing techniques in order to avoid detection. Metamorphism is the ability of a program to mutate its form yet keeping unchanged its functionality and therefore its danger in case of malware. A major challenge in this field is the development of general automatic/systematic detec...

This work evaluates an exceptionally complex natural laboratory, the Middle Triassic Latemar isolated platform in northern Italian Dolomite Mountains and explores spatial temporal gradients processes products related to contact metamorphism, dolomitization dedolomitization of marine limestones. The relation between petrographic change re-equilibration geochemical proxy data is evaluated from pe...

Massif-type anorthosite and comagmatic associations of rutile-bearing ilmenitite (RBI) oxide-apatite-rich amphibolite (OARA) from the Chiapas Massif Complex (CMC) in southeastern Mexico display a protracted billion-year accessory mineral record encompassing magmatic crystallization at c. 1.0 Ga to recent ductile shear deformation 3.0 Ma. Multiple discrete zircon populations between these age en...

a brief account of the representative and workable industrial minerals namely magnesite, talc and barite in lesser himalaya, is presented here emphasizing their genesis. deposits of magnesite and talc are found associated with neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner lesser himalayan sequences. field, textural, geochemical signatures and fluid inclusi...

Almost all meteorites (about 99% by number) are samples from a few hundreds of asteroids that are leftover from planetesimals and protoplanets formed within several million years after the birth of the Solar System. These meteorites record detailed evolutionary history of dust to planets, including condensation, accretion, aqueous alteration, thermal metamorphism, partial and total melting.
