Pit with ceramic wasters (AFK13, S27, find inventory number 100). This particular site is part of a larger project: Fluxys – tracé Alveringem-Maldegem
Deelzone Lot 1&2 Lo-Reninge - Staden. Permit code: 2014/286 en 286 (2).
Dark brown reduced fabric; dark brown (PPL), black (XP).
Homogenous matrix, non calcareous without optical activity.
- ca. 35-50%
Inclusions
Quartz (++; mono, poly, r-sr, silt - medium sand, weathering, alteration), feldspars (-; plagioclase; sr-r, ff), muscovite mica (+; el, ff), O/Fe (+-), semi-plastics/clay pellets (+-; iron-rich with fine inclusions), biotite/hornblende (--; uncertain: colorless in PPL, bright green&pink (2nd order) in XP, r, ff), amphibole/pyroxene (possible singular grain).
The coarse fraction varies from medium to fine sand, the fine fraction from very fine sand to silt. Possible bimodal. Grains are generally sub-rounded to rounded. Overall the fabric is poorly to very poorly sorted.
- ca. 40-50%
Voids
Many small planar voids in main fabric, well aligned parallel to edge, no infill; large planar voids and vughs in semi-plastics/clay pellets with surrounding drying cracks around.
- ca. 10-15%
Diagnostic features
The fabric is characterized by a homogenous reduced matrix with no optical activity and moderate porosity. Dominant quartz inclusions with frequent muscovite mica, common opaques/iron oxides and semi-plastics/clay pellets, few feldspars, rare biotite/hornblende (?), and a singular amphibole/pyroxene. Possibly slightly bimodal. Overall poorly to very poorly sorted.
Additional information
Bright green (xp) minerals are most likely hornblende or biotite mica. Also observed in A0003 and A0005.
