The design and operation of a Thin-Cloud Rotating Shadowband Radiometer (TCRSR) described here was used to measure the radiative intensity of the solar aureole and enable the simultaneous retrieval of cloud optical depth, drop effective radius, and liquid water path. The instrument consists of photodiode sensors positioned beneath two narrow metal bands that occult the sun by moving alternately...

Major, minor, and trace element geochemistry as well iron oxidation state isotopes were investigated in serpentinites olivine-talc fels present along a metamorphic gradient the Bergell contact aureole (Central European Alps) to evaluate mobility during serpentine. This is an ideal target study dehydration of mantle rocks due increase temperature from greenschist facies conditions (350°C) amphib...

The main observations of 1761 by M. Lomonossov and those that followed are recalled extending the discussion to other remarkable visual passages, then with more powerful imagers producing images in profusion. modern treatment parasitic effects is briefly focusing on expert observation which has recently been widely commented criticized. It included a spurious effect called “black drop effect”. ...

Abstract Petrographic observations combined with mineral compositional analyses constrain the phase relations of prograde metamorphosed serpentinites in Bergell contact aureole (Italy). In a 1500 m profile perpendicular to north-eastern edge intrusion, seven dehydration reactions ran completion. Three previously undocumented have been identified within 70 intrusive contact: olivine + anthophyll...
