ASTEROIDS ASTEROIDS COMPOSITION SPECTROSCOPY
2012/2/21
We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids ...
U-Pb zircon ages of syenitic and granitic rocks in the Ashizuri igneous complex, southwestern Shikoku: Constraint for the origin of forearc alkaline magmatism
U-Pb age zircon LA-ICP-MS Miocene alkaline magmatism Southwest Japan Outer Zone
2017/8/9
We report two first U-Pb zircon ages of the felsic rocks in the Ashizuri igneous complex, southwestern Shikoku, using the LA-ICP-MS. Samples are a syenite (ASH54) and a biotite granite (ASH5). Weighte...

CHEMISTRY OF GROUNDWATER IN IGNEOUS ROCK AT ANGERED,GOTHENBURG
CHEMISTRY OF GROUNDWATER IGNEOUS ROCK
2009/10/29
Within an area of about 5 km2, 25 wells were drilled to depths of about
90 m for groundwater observation. The wells were sampled and analyzed,
and from the results it could be concluded that the ion...
Chemical changes in water circulating deep in the fissures of the solid
rock are studied. The ultimate chemical composition is determined by
the conditions of percolation through the soil zone. For ...
