- Comparable thin section(s)
- Matrix
-
Reduced light to dark brown fabric; light and dark brown (PPL), black (XP).
Semi-homogenous matrix, non-calcareous with low optical activity.
- ca. 40-65% - Inclusions
-
Quartz (++; mono, poly, cf: r-sr, fine to medium sand + coarse sand outlier, ff: sr-sa, very fine to fine sand), sedimentary rock detritus (+; quartz arenite), chert/flint (+), metamorphic rock detritus (+-; low grade, sedimentary parent rock), feldspars (+; plagioclase, microcline, r-sr, cf & ff), muscovite mica (+; ff, el), amphibole/pyroxene (-; r, ff, weathered), glauconite (+; r-sr, ff, red in PPL), O/Fe (+), semiplastics/clay pellets (+, iron-rich).
The coarse fraction consists of fine to medium/coarse sand, the fine fraction consists of fine to very fine sand. Grains are generally rounded to subangular. Overall the fabric is poorly sorted and poorly orientated, close to double spaced.
- ca. 30-40% - Voids
-
Many planar voids, channels and vughs of various sizes, moderate alignment relative to the edge. Zones and layers of diffuse secondary calcite: micritic calcite crystals deposited through voids forming layers and patches.
- ca. 15-20% - Diagnostic features
- The fabric is characterized by a semi-homogenous reduced matrix with no optical activity and high porosity. Dominant quartz inclusions with frequent sedimentary rock detritus, chert/flint, feldspars, muscovite mica, glauconite, opaques/iron oxides and semiplastics/clay pellets, common metamorphic rock detritus, and few amphibole/pyroxene. Overall poorly sorted fabric.
