Introduction: Lunar mare basalts are products of partial melting of the lunar interior, thus are keys to understand the chemical compositions of the source mantle. However, the iron-enrichment of the mare basalt samples returned by Apollo and Luna missions, compared to the terrestrial basalts, have led to an inference that the mare basalt hand specimen do not represent the primary magma composi...

[1] Moon Mineralogy Mapper (M) image and spectral reflectance data are combined to analyze mare basalt units in and adjacent to the Orientale multiring impact basin. Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The...

Basalt continuous fibers are regarded as an inert and naturally occurring material that is produced from basalt rock by using single component raw material and drawing and winding fibers from the melt. Basalt based materials are environmentally friendly and nonhazardous. Basalt FRP (BFRP) composites as a reinforcement not only display a higher strength and modulus, but also a similar cost, and ...

Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...

Ancient lunar volcanic deposits, known as cryptomaria, have been detected by remote telescopic and orbital measurements since the 1970s. Cryptomaria are most easily identified by the presence of darkhalo impact craters and are associated with a mare basalt mineralogy, which is indicated by two pyroxene spectral absorption features near 1 μm and 2 μm in the visible to near-infrared (VNIR) wavele...

Magmatism during the maturation phase of Archean greenstone belts produced voluminous tonalite–trondhjemite–granodiorite (TTG) suites, as well a lesser amount tonalite–trondhjemite–diorite (TTD) suites. Such TTD suites have recently been recognized in Abitibi belt, on southern flank Superior Craton, Canada, but their source(s), differentiation processes, and depths emplacement remain poorly con...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...

The Sonju Lake intrusion (SLI) is a 1200-m thick, sheet-like, tholeiitic layered intrusion located within the 1096 Ma Beaver Bay Complex of NE Minnesota. Its cumulus stratigraphy of Ol Pl+Ol Pl+Cpx+Ol Pl+Cpx+Ox±Ol Pl+Cpx+Ox+Ol+Ap indicates formation by closed-system fractional crystallization of a tholeiitic magma. In 1999, outcrop sampling revealed a stratiform PGE-enriched interval within oxi...

Microbe-mineral interactions have become of interest for space exploration as microorganisms could be used to biomine from extra-terrestrial material and extract elements useful as micronutrients in life support systems. This research aimed to identify the impact of space flight on the long-term survival of Cupriavidus metallidurans CH34 in mineral water and the interaction with basalt, a lunar...

A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t ha 1 each). Results showed that so...
