Moses Rock dike is a Tertiary diatreme containing serpentinized ultramafic microbreccia (SUM) located on the Colorado Plateau in Utah. Field evidence indicates that SUM was emplaced first followed by breccias derived from the Permian strata exposed in the walls of the diatreme and finally by complex breccias containing basement and mantle-derived rocks. SUM is primarily found dispersed througho...

Article history: Received 23 September 2016 Received in revised form 31 January 2017 Accepted 7 February 2017 Available online 9 February 2017 Volcanic eruptions on theMoon take place in conditions of low gravity and negligible atmospheric pressure, very different from those on Earth. These differences lead to characteristic lunar versions of hawaiian and strombolian explosive activity, and to ...

Dike swarms are the fossil remains of regions crust that have undergone repeated magma injections. Volcanic earthquake and geodetic measurements are, at least in part, a record active injection fluids (water, gas, or magma) into fractures. Here, we link these two ways observing magmatic systems by noting dike thicknesses magnitudes share similar scaling parameters. In Jurassic Independence swar...

Three new heteroleptic copper(II) complexes, [(tmen)Cu(dike)H2O]X where tmen = N,N,N',N'-tetramethylethylenediamine, dike = 2-acetylcyclopentanone anion and X= ClO4- (1), Cl- (2) and Br- (3) are prepared and characterized by elemental analyses, molar conductance measurements and IR and UV-Vis spectroscopy techniques. The complex 1 is fairly soluble in various organic solvents and demonstrates d...

Dike-pond is a unique agricultural landscape type in the Pearl River Delta region of China, which has significance for maintenance ecological balance. In recent years, urbanization China developed rapidly, and dike-ponds have been extensively occupied, reducing their regulation ability threatening regional security. Taking Shunde District Foshan as an example, based on remote sensing images fro...

Figure 1. Relief map of island of Hawaii (after Moore et al., 1995) showing locations of dive sites (triangles, except dive 389, which is a square), locations of shield volcanoes (L—Loihi, K—Kilauea, ML— Mauna Loa, H—Hualalai, MK—Mauna Kea, Ko—Kohala), areas of recent Kilauea eruptions along south coast of Hawaii (u—Mauna Ulu, p—Puu Oo), rift zones of Mauna Loa (parallel lines), large, ca. 100 ...

We model the ascent and eruption of lunar mare basalt magmas with new data on crustal thickness and density (GRAIL), magma properties, and surface topography, morphology and structure (Lunar Reconnaissance Orbiter). GRAIL recently measured the broad spatial variation of the bulk density structure of the crust of the Moon. Comparing this with the densities of lunar basaltic and picritic magmas s...
