Ecosystems on cangas (duricrust) present considerable heterogeneity of habitats due to microtopographic variations, soil accumulation and a variety of plant functional groups. Therefore, spatial and ...

前者以>50米厚的风化剖面为特征，后者则是连接分水岭与河流的侵蚀-搬运斜坡。 铁质硬壳（duricrust）的时空分布成为解码古气候的关键指标。 靶区与方法 布基纳法索Goren绿岩带因其完整的风化层序列成为西非形态-成土作用（morpho-pedogenesis）研究的理想靶区。

Excludes recent Quaternary alluvial systems (land zone 3), exposed duricrust (land zone 7), and soils derived from underlying bedrock (land zones 8 to 12). Soils are usually Tenosols and Kandosols, ...

祝融号火星车着陆区位于经历了重塑事件的年轻亚马逊纪地层上，已有的研究认为火星在亚马逊纪时期气候寒冷干燥，液态水活动的范围和程度十分有限。祝融号在地质年代较为年轻的着陆区发现水活动的迹象表明，亚马逊纪时期的火星水圈可能比以往认为的更加活跃。该发现对理解火星的气候环境 ...

Analytical approaches that preserve the endogenous state of the examined system are essential for the in vivo study of bioinorganics. X-ray fluorescence microscopy of biological samples can map ...

Following the results of this infill geochemical program, the Company intends to further validate these results with trenching and, in areas of significant duricrust, shallow scout RC drill programs.

Because the encrusted Martian soil (aka “duricrust”) extends to a depth of 20 cm (~8 inches), the Mole managed to penetrate just a little more than 40 cm (~16 inches)—well short of its 5 m ...

Therefore, the solidification of this brine is the most likely explanation for the duricrust layer beneath the surface.

When penetrating the duricrust, the mole created a hole as it hammered and therefore failed to generate enough friction in the upper 20 centimetres. The duricrust soil is covered by one to two ...

The Altar Stone, a 6-ton sandstone megalith that sits at the center of Stonehenge’s iconic stone circle, was sourced at least 750 km from its current location, according to new research led by Curtin ...

Calcrete, the calcium carbonate duricrust generally occurs in arid/semiarid region. Globally, it has been used as a non-traditional constructional material. The recent discovery of calcrete hosted ...
