The global distribution map of basalt samples is shown in Figure 4. Each basalt sample was assigned with 11 major elements (SiO2, Figure 4.

Hand sample of Basalt, an extrusive igneous rock composed of calcic plagioclase feldspar, pyroxene, and occasionally olivine. Accessory minerals are sometimes visible. Basalt has an aphanitic (microcrystalline) texture; the mineral grains are too …

Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.

Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene (augite) and iron ore (titaniferous magnetite). Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is …

The basalt based refractory filler was obtained by crushing and grinding selected samples of basalt rock. XRD, SEM and optical microscopy methods were used to characterize the obtained filler...

The atlas contains information about the type of sample (e.g., rock, soil), the lithology (e.g., basalt, norite), and a description of the sample. Links to additional information about each sample are provided for those that have been previously described in The Lunar Sample Compendium and Lunar Sample Catalogs.

A general term used to label a rock sample. It is a useful way of grouping similar samples throughout a collection. Category names are often, but not exclusively, common rock names (e.g. granite, basalt, dolerite, gabbro, greisen, skarn, gneiss, amphibolite, limestone, sandstone).

2025年1月1日 · In this paper, a series of non-destructive microscopy and spectroscopy techniques were used to investigate the physical properties and mineralogical characteristics of a basaltic clast sample obtained from one of the drilling operations of the Chang'e-5 lunar soil research sample.
