The host sandstone samples lay in the arkose field in the Q-F-L triangular diagram (Fig. 6 l). No significant alteration was observed in the feldspar. The lithic fragments consist of igneous and metamorphic rock fragments. The sandstones show little mechanical compaction and cementation (<1%).Lithic sandstones can have a speckled (salt and pepper) or gray color, and are usually associated with one specific type of lithic fragment (i.e., igneous, sedimentary, or metamorphic). [1] Tectonically, lithic sandstones often form in a wide variety sedimentary depositional environments (including fluvial , deltaic , and alluvial sediments ... Lithic sandstones, or lithic arenites, or litharenites, are sandstones with a significant (>5%) component of lithic fragments, though quartz and feldspar are usually present as well, along with some clayey matrix. ...

Clastic sedimentary rocks in which a significant proportion of the clasts are larger than 2 mm are known as conglomerate if the clasts are well rounded, and breccia if they are angular.Members 2, 4, and 6 of the Xujiahe Formation are mainly composed of gray medium-grained, medium-fine-grained lithic arkose, arkose lithic sandstone, and lithic quartz sandstone, which are the main reservoir segments of the Xujiahe Formation. The second Member of the Xujiahe Formation is the best reservoir in the Hechuan gas field.Độ hạt của cát kết arkose và lithic arkose thay đổi từ cát hạt mịn đến thô với kích thước hạt phổ biến thay đổi trong khoảng 0.125mm - 1.0mm. Trong khi cát kết feldspathic greywacke phổ biến là cát hạt mịn đến trung với kích thước hạt phổ biến thay đổi trong khoảng 0.125mm -Arkose is sandstone with significant amounts of feldspar, usually greater than 25%. Sandstone that contains feldspar, which weathers more quickly than quartz, is useful for analyzing the local geologic history. Greywacke is a term with conflicting definitions . Greywacke may refer to sandstone with a muddy matrix, or sandstone with many lithic ...

Another name for a lithic wacke is greywacke. Figure 5.7 shows thin sections [2] (microscopic views) of quartz arenite, arkose, and lithic wacke. In the images, quartz grains are marked Q, feldspar grains are marked F, and lithic fragments are marked L. Notice the relative abundances of each component in the three types of rocks. Lithic fragments are of igneous, sedimentary, and metamorphic rocks. Grains are moderate to poorly sort (Figs. 6c, d, 7c, d). ... Arkose and lithic arkose microfacies and conglomeratic and medium ...The Palaeogene tight gas sandstone reservoirs consist of limy, limy fine lithic and medium lithic sandstone or arkosic lithic arenite with quartz content of 56–64%, feldspar of 11–18% and lithic fragments of 21–29%. The cement, totaling 6.3%, is dominated by clay and calcite with minor quartz overgrowth. ….

Clastic sedimentary rocks in which a significant proportion of the clasts are larger than 2 mm are known as conglomerate if the clasts are well rounded, and breccia if they are angular.A feldspar-rich sandstone is called an arkose. Lithic rich sandstones are called litharenites. Further subdivisions are shown in the diagram. If the rock has between 10 and 50% clay matrix, the rock is called a wacke. Quartz wackes have predominantly quartz surrounded by a mud or clay matrix. In a feldspathic wacke, feldspar is more abundant ...
