- Matrix
-
Reduced light grey fabric with dark grey edges; dark brown (PPL), black (XP).
Semi-heterogeneous matrix, non-calcareous with no optical activity.
- ca. 40-55% - 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 (+-; possible quartz arenite, some slightly metamorf), chert/flint (+-), feldspars (+-; plagioclase, microcline, r, cf), muscovite mica (+-; cf & ff, el), 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 to very poorly sorted and moderately to poorly orientated, single 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-heterogeneous reduced matrix with no optical activity and high porosity. Dominant quartz inclusions with frequent opaques/iron oxides and semiplastics/clay pellets, common sedimentary rock detritus, chert/flint, feldspars and muscovite mica. Overall poorly to very poorly sorted fabric.
