Karst topography is formed from the dissolution of soluble rocks, such as limestone and dolomite. In soils of such a landform, excessive contents of exchangeable calcium seriously limit the growth of vegetations. Researches have proved that rhizosphere microorganisms and endophytes help host plants to adapt to various adverse environments. The adaptive capacity of plants that grow in adverse en...

It has been proposed that Oligo-Miocene regional uplift of Madagascar was generated and is maintained by mantle dynamical processes. Expressions include flat-lying Upper Cretaceous-Paleogene marine limestones crop out at elevations hundreds meters along the western seaboard emergent Quaternary coral-rich terraces rim coastline. Here, we explore history subcrustal topographic support through a c...

The data acquired and interpreted across the sixty (60) VES points of study was used to evaluate agricultural viability land. terrain is underlain by four five geologic layers comprised topsoil (of average resistivity 320Ωm), which heart activities. soil conductivity evaluated from first three with an value 3.13, 0.49 7.5 for first, second third respectively, all measured in milliSiemens per me...

Multichannel seismic-reflection data collected on the Peru margin as part of Leg 112 of the Ocean Drilling Program predrilling site survey define some tectonic and sedimentary features of the Lima and Yaquina basins. A narrow accretionary prism is imaged at the toe of the trench slope in both areas. Landward of the accretionary prism is a transition zone that may be underlain by older accreted ...
