Characteristics of lithofacies exposed in the Roman Valley Quarry.
Lithofacies
Thickness
(%)
(mD)
Bitumen distribution
Au:
Alternation of medium- to coarse-grained bioclastic grainstones (Au1) and medium-grained bioclastic grainstones (Au2).
40 to 60 m
~27.5
83.13 (V) 160.09 (H)
Abundant in both matrix and fractures near faults
B:
Medium-grained grainstones.
10-to 15-m
~26.4
444.82 (V) 530.94 (H)
Abundant in both matrix and fractures near to faults
C:
Alternations of two echinoid plates and spines rich facies: fine-grained bioclastic grainstones (C1) and fine- to very fine-grained bioclastic packstones (C2). Argillaceous to marly beds (<3 cm thick) are common.
10 to 15 m
~10.9
~0.30 (V) ~2.51 (H)
Absent in matrix and oil stain in fractures
E:
Alternation of two planktonic foraminifera facies: marly wackestones (E1) and marly mudstones (E2).
60-65-m
~28.8
~0.085 (V) ~0.081 (H)
Absent in both matrix and fractures
Notes: lithofacies description from Rustichelli et al. [56], matrix porosity () obtained with helium pycnometer and gas permeability () measurements (performed in both horizontal, H, and vertical, V, direction) were reported by Volatili et al. [13]. Bitumen distribution from field observations [13, 54, 56].
