Siliciclastic - Wikipedia
Siliciclastic (or siliclastic[1]) rocks are clastic non carbonate sedimentary rocks that are composed primarily of silicate minerals, such as quartz or clay minerals. Siliciclastic rock types include mudrock, sandstone, and conglomerate. [1][2]
Siliciclastic Rocks - Geology is the Way
Siliciclastic rocks, also known as terrigenous, detrital, or clastic rocks, are a group of sedimentary rocks consisting of fragments of minerals and rocks derived from pre-existing rocks. Such fragments are termed clasts, regardless of their composition and size.

2022年12月16日 · The term siliciclastic refers to sediments composed mostly of silicate minerals. The most common sedimentary rocks – including shale, sandstone, and conglomerate – form from siliciclastic sediments.
Siliciclastic rock | geology | Britannica
…are also referred to as siliciclastic sedimentary rocks. Siliciclastics are further subdivided on the basis of clast diameter into conglomerate and breccia, sandstone, siltstone, and finer-than-silt-sized mudrock (shale, claystone, and mudstone).
5: Siliciclastic Sedimentary Rocks - Geosciences LibreTexts
Siliciclastic sedimentary rocks are made of solid particles that were transported as suspended load, bedload, or under the direct influence of gravity. In all cases, the clastic particles will settle and come to rest when motion ceases.
SILICICLASTIC ROCKS 1. SANDSTONES 1.1 Introduction 1.1.1 Sandstones are an important group of sedimentary rocks. I suppose a good estimate of the percentage of sedimentary rocks that would be classified as sandstones is about 25%. 1.1.2 Defining what's meant by the term sandstone turns out not to be easy.
Clastic Sedimentary Rocks: Examples with Photos – Geology In
Siliciclastic rocks are clastic sedimentary rocks, meaning they are formed from fragments of pre-existing rocks. Siliciclastic rocks are most commonly composed of silicate minerals, such as quartz, feldspar, and mica.
Clastic rock - Wikipedia
Siliciclastic rocks are clastic noncarbonate rocks that are composed almost exclusively of silicon, either as forms of quartz or as silicates.

2015年6月3日 · Siliciclastic (commonly referred to as clastic) rocks are composed of terrigenous material formed by the weathering of pre-existing rocks, whereas carbonate rocks are composed principally of sediment formed from seawater by organic activity.
5.5: Classification of Sedimentary Rocks - Geosciences LibreTexts
2024年4月11日 · The clastic sediment is often referred to as “siliciclastic” because it is derived from the rocks of the crust which, as we have learned, is largely composed of silicate minerals of igneous rock. Clastic (or detrital) rock is classified and named based on …
