Despite the fact that rock glaciers are one of the most common geomorphological expressions of mountain permafrost, the impacts of their solute fluxes on lakes still remain largely obscure. We examined water and sediment chemistry, and biota of two neighboring water bodies with and without a rock glacier in their catchments in the European Alps. Paleolimnological techniques were applied to trac...

Hard rock aquifers for the purpose of this Paper mean the non-carbonate, fractured rock aquifers in the terrain covered by crystalline basement complex, metamorphic rocks and also by extensive effusive volcanic rocks like the basalts of western India (Deccan traps. Ground water development in hard rock aquifer areas has always played a secondary role compared to that in the areas having high-yi...

Abstract This study presents petrographic and geochemical characterization of 46 pre-impact rocks 32 impactites containing and/or representing impact melt rock from the peak ring Chicxulub structure (Yucatán, Mexico). The aims were both to investigate components that potentially contributed (i.e., lithologies) better elucidate emplacement at Chicxulub. presented here are subdivided into two sam...

Enhanced geothermal system (EGS) is the primary means during Dry Hot Rock development. It necessary to build an underground heat exchange area its construction, and temperature of rock will change significantly, thus, mechanical properties those rocks be affected. In order judge whether under are related crystal structure granite, we firstly used crystalline heterogeneity coefficient H describe...

We recently identified a novel human protein kinase, p160 ROCK, as a putative downstream target of the small GTPase Rho. Using the human ROCK cDNA as a probe, we isolated cDNA of two distinct, highly related sequences from mouse libraries. One encoded a mouse counterpart of human ROCK (ROCK-I), and the other encoded a novel ROCK-related kinase (ROCK-II). Like ROCK/ROCK-I, ROCK-II also bound to ...

Introduction. FIDO is the prototype rover for the Mars 2003 mission, complete with an Athena-like science payload [1]. FIDO will be deployed in April 1999 for a series of tests at Silver Lake, CA [2]. In preparation for these tests, we have examined a suite of rocks collected at the site to anticipate the problems expected in field analyses on available rock surfaces as opposed to surfaces that...

The 80-km-wide Vredefort dome is a deeply eroded remnant of the central uplift of the Vredefort Impact Structure. It exposes upturned Archean to Paleo-proterozoic supracrustal strata and a core of Archean crystalline gneisses that have previously been interpreted as an on-edge profile of the crust and upper mantle. Our structural analysis of the gneisses in the core of the dome indicates that s...
