Corroborative evidence for Holocene reverse-slip on the eastern Big Pine fault is ∼ 1 m of incised bedrock that is characteristically exposed beneath 2 3.5 ka fill terraces in tributaries south of the fault.
A contaminant plume containing TCE and its daughter products were detected downgradient from the buried waste pits, with most of the contamination occurring in the upper 6 m of the bedrock.
Thus, for the tallest fractures, 1000 to 2000 m of intact bedrock remained above the upper edge of the fracture zone.
There are certainly instances of upward head gradients in the vicinity of some black shales, however, high upward head gradients would need to be sustained over thick sequences (typically >1000 m) of highly permeable bedrock to drive a significant amount of brine into shallow fresh groundwater.
Steeply rising apparent resistivity values of VES-12 for larger electrode spacing (AB/2 > 250 m) indicates the appearance of bedrock.
Their results showed that the largest depth of the bedrock is about 500 m, and the shape of bedrock in the Puli basin is roughly symmetrically concave.
The depth of bedrock varies from 155 m at KPN to 440 m at THM.
Support for the bridge is provided by barrettes that pass through 30 m of superficial Quaternary formations into bedrock strata of the Carboniferous Bettisfield Formation.
On leaving Pool Malebo an annual discharge of 1250 x 10 m of water plunges in a bedrock-constrained channel through intermittently narrow (<0.2 km) and wide (>2 km) gorges.
