Research on the populations of rice grain bug Paraeuscosmetus pallicomis Dallas (Hemiptera: Lygaeidae) in paddy field ecosystems was performed with the aim to determine the populations of rice grain bug in weed-free paddy field, weedy paddy field, and paddy dykes. Experiment was carried out in the village of Paccellekang in the district of Patallasang of Gowa Regency in South Sulawesi, Indonesi...

The occurrence of plate tectonic processes on Earth during the Paleoproterozoic is supported by ca. 2.2–1.8 Ga subduction-collision orogens associated with assembly Columbia-Nuna supercontinent. Subsequent supercontinent breakup evidence global 1.8–1.6 large igneous provinces. North China craton notable for containing along its margins, herein named Northern Margin orogen, yet nature and timing...

Findings of coesite and microdiamond in metamorphic rocks of supracrustal protolith led to the recognition of continental subduction to mantle depths. The crust-mantle interaction is expected to take place during subduction of the continental crust beneath the subcontinental lithospheric mantle wedge. This is recorded by postcollisional mafic igneous rocks in the Dabie-Sulu orogenic belt and it...

Mafic Mound” is a distinctive and enigmatic feature 75 km across and 1km high near the center of the vast South Pole-Aitken Basin (SPA). Using several modern data sets, we characterize the composition, morphology, and gravity signature of the structure in order to assess its origin. Mafic Mound is found to exhibit a perched circular depression and a homogeneous high-Ca pyroxene-bearing composit...

Introduction: Lunar meteorite Dhofar 961, a complex, lithic-clast-rich impact breccia [1,2], was called out by [3-6] as a candidate for an origin in the South Pole – Aitken (SPA) Basin region of the Moon (the SPA Terrane) on the basis of its relatively mafic, but nonmare lithologic and major-element chemical composition. It also has an incompatible-element signature that differs from the KREEP-...

Large Ra excesses in a number of mafic arc magmas, and geophysical observations of earthquake hypocenters locations, indicate that mafic melts can get transferred from source to surface within days to ~1 kyr. Decreasing Ra–Th disequilibria with increasing SiO2 in co-magmatic suites of individual arc volcanoes suggest that magma differentiation often occurs on timescales of a few thousand years ...

Major element compositions of glass inclusions in olivine and plagioclase phenocrysts from representative Mariana arc lavas show that mafic Mariana arc liquids are tholeiitic and not high-alumina, implying that the high-alumina characteristic of these lavas reflects accumulation of plagioclase. Glass inclusions also show the common occurrence of felsic melts previously unrecognized among Marian...

Movement data resulting from tracking positions of various moving objects (people, animals, goods, etc.) have recently got close attention of researchers. Methods for analysis of movement data have been developed in the areas of geographic information science (Buliung and Kanaroglou 2004), geovisualization (Dykes and Mountain 2003), information visualization (Kapler and Wright 2005), data minin...
