AAPG Store. Lithological determination from wireline logs is often done by sophisticated computer programs, but basic quick-look interpretation can be made by visual inspection of appropriate logs. The best logs for lithological purposes are those that are (1) most influenced by rock properties and (2) least influenced by fluid properties.31 Domes and Basins . Elizabeth Johnson. Domes.

Diabase - the rock selected for Stonehenge and transported 240 miles in 2100 BC.Strike and dip. In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from horizontal. [1]Below are examples of the symbols used in geologic diagrams and maps to represent specific kinds of rocks. If bedding, cross-bedding, ripples, fossils, distortion, or certain materials are present in the rock, the symbols are altered. To download the complete list of standard symbols, click here. Gravel/conglomerate. Breccia.Figure 1. Fault, fault zone, shear zone. Shear zones are zones of intense ductile deformation that are thin relative their lateral extent. Shear zones, like faults, typically show offsets of older structures, but unlike faults, they lack through-going brittle fractures. In practice, faults and shear zones are closely related.An animation of the inner Solar System planets' orbit around the Sun. The duration of the year is the time taken to go around the Sun.

A setting that determines the drawing order of features based on their symbol properties.Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps. Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped.

Creating adequate symbolization of a geologic map ...Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols.

From these data and the routine-core-analysis data, …Strain is a measure of the change in shape or size of an object relative to its original shape or size. For example, the change in length of a spring, Δ L relative to the original length of the spring, L describes the strain of the spring, ϵ = Δ L / L. Both Δ L and L must be measured in the same units (e.g., cm or mm).The key thing is that a way-up structure must be display some difference between its top and its bottom. They always look different up-side-down compared to right-side-up. In sedimentary rocks, the following way-up structures can aid the historical geologist in figuring out the paleo-“up” direction: cavity fills.The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or paleontological events.Strike and dip map symbols look like the capital letter T, with a short trunk and extra-wide top line. The short trunk represents the dip and the top line represents the strike. Dip is the angle that a bed or layer plunges into the Earth from the horizontal. A number next to the symbol represents dip angle. Figure 2.
