Abstract One outcrop of the NE–SW-trending fault with a steep occurrence and grown gouge was discovered in north segment Tangshan zone during field survey near Jujialing village on Kaiping-Guye boundary Hebei province, North China. This has received less attention seismic geologic surveys. In addition, three neighboring parallel NE trending scarps heights range 1–1.5 m were generally flat terra...

The widespread application of drones and associated miniaturization imaging sensors has led to an explosion remote sensing applications with very high spatial spectral resolutions. 3-D ultrahigh-resolution digital outcrop models created using oblique imagery from ground-based are now commonly used in the academic industrial sectors, while generation spatially accurate been greatly facilitated b...

Summary We present a revision of the three species Tristachya in Madagascar. The tussock-forming T. betsileensis is rare endemic quartz outcrops Itremo Protected Area. rhizomatous isalensis and humbertii are common components sandstone outcrop vegetation Isalo National Park. A new combination made. Descriptions, conservation assessments, illustrations, distribution map presented.

The Brassfield Formation, consisting mainly of carbonate strata, is overlain by beds of the Dayton Formation at several localities in southwestern Ohio, high on the east flank of the Cincinnati Arch. The Brassfield thickens eastward into the subsurface and becomes separated from the Dayton by an expanding wedge of shale and carbonate beds. The writer considers these beds to be equivalent to the...

Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

Basaltic glasses (hyaloclastite) are a widespread habitat for life in volcanic environments, yet their interior physical conditions are poorly characterized. We investigated the characteristics of exposed weathered basaltic glass from a surface outcrop in Iceland, using microprobes capable of continuous sensing, to determine whether the physical conditions in the rock interior are hospitable to...

Introduction. Venus' ribbon tessera terrain [1,2] (rtt) records ancient environmental conditions significantly different than contemporary Venus [3,4], and geologic relations are consistent with rtt representing the oldest locally exposed unit across Venus [5], although individual tracts of rrt may have formed at differnet times [6]. We have constructed a global geologic map of rtt exposures an...
