Archean volcanic rocks in the mafic-dominated, ca. 2.66–2.69 Ga Point Lake and Beaulieu River belts, Slave Province, Northwest Territories, are significant in demonstrating the facies that characterize specific portions of pillow volcanoes or seamounts, irrespective of tectonic setting. Three distinct localities mapped in detail display facies consistent with: (1) proximal, deep-water, (2) medi...

Introduction: There is abundant geomorphic evidence for the importance of groundwater in the Martian hydrologic cycle. It appears likely that the valley networks formed as a result of groundwater sapping [1], and it is clear that the outflow channels are the manifestation of large-scale eruptions of groundwater to the surface [2]. Thus, our understanding of the formation of these features is on...

Abstract Geothermal energy is one of the mainstay future alternative in Indonesia. One area that believed to have geothermal potential Telaga Tujuh Warna Village Lebong Regency, Bengkulu Province, Manifestations hot springs, mud pools, geysers, sulfur, and presence steam around lake are our beliefs about existence sources area. The purpose this study was determine stratigraphic characteristics ...

Petrographically and chemically well-characterized rocks of the Apollo 14 landing site (12 impact melt breccias, 3 clast-free impact melt rocks, 2 granulitic rocks, 1 cataclastic noritic anorthosite, 1 shocked gabbronorite, 1 mare basalt, and 1 plagioclase single crystal) have been dated by the 40Ar-39Ar technique. The samples represent two different formations at the Apollo 14 site: (1) small ...

The utilization of rocks as fertilizers is limited by their low solubility. However, solubilization may be achieved by some micro-organisms, such as ectomycorrhizal fungi (ECMf). The aim of this study was to evaluate the potential of seven isolates of ECMf to solubilize two rocks, alkaline breccia and granite, and to liberate potassium and phosphorus for Eucalyptus dunnii seedlings under greenh...

NWA 2700 and NWA 2977 Paired With NWA 773: NWA 2700 is a 31.7 gram stone consisting of small gabbro clasts plus regolith breccia matrix (see Figure 1). The olivine gabbro contains ~50 vol.% olivine (Fa29.3-34.7; FeO/MnO = 94), pigeonite (Fs2228.3Wo5.6-10; FeO/MnO = 52), augite (Fs13.2Wo38.5), plagioclase and minor maskelynite (An89), Ba-rich alkali feldspar (Or92An4, BaO up to 8.9 wt.%), Crspin...

Introduction: The Rochechouart impact structure is a deeply eroded, late Triassic impact site located in south-central France [1,2]. Rochechouart impactites comprise five main lithological units from the base of the structure upwards, originally described as follows: unit 1) shocked autochthonous basement rock; unit 2) finely crystalline melt rock; unit 3) red 'welded' breccia/suevite; unit 4) ...
