Rock unit.

The gray rock units are impermeable shale. Oil and natural gas forms within these shale units and then migrates upwards. Some of the oil and gas becomes trapped in the yellow sandstone to form an oil and gas reservoir. This is a "conventional" reservoir - meaning that the oil and gas can flow through the pore space of the sandstone and be ...The symbol for each rock or sediment unit is shown in a box next to its name and brief description. These symbols are stacked in age sequence from oldest at the bottom to youngest at the top. The geologic era, or period, or epoch-the geologic age-is listed for each rock unit in the key. By stacking the units in age sequence from youngest at ...identify each soil and rock unit of engineering significance, and must provide recommended design parameters for each of these units.

Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the ...

The layers of rock beneath the earth's surface also are compartmentalized into convenient segments. A formation is the fundamental rock unit used in mapping, and consists of an essentially uniform rock type that can be distinguished from adjacent, underlying or overlying rock units at sight.

Geological maps are typically divided into areas of different colours (for different rock units) that are bounded by lines; these lines on the map are the traces of the geological surfaces that separate the units. The intersection of a fault plane with a planar rock unit that the fault displaces produces a line called the fault cut-off or cutoff. This is basically a very old (approximately 300 million-year-old) rock unit that contains other rocks and fossils dating back to the Mississippian period.
