Sentence examples for sections of rocks from inspiring English sources

The laboratory work was based entirely on thin sections of rocks, and students were required to make sketches and colored drawings to record their observations.

Convinced of the value of the microscope as a tool in all sciences, Sorby began to prepare thin sections of rocks (about 0.025 millimetre, or 1/1000 inch thick) for microscopic study in 1849.

2D grain growth simulations are essentially the computational imitation of experimental thin sections of rocks.

To eliminate that, the Corps has started removing sections of rock from some groins on New Jersey's shore so sand can flow more freely.

"We would hit these blank sections of rock, where I was sure there was nowhere else to go, but then Jimmy or Conrad would launch into the void," says Ozturk.

Many structures can be examined microscopically, using the same general techniques employed in petrology, in which sections of rock mounted on glass slides are ground very thin and are then examined by transmitted light with polarizing microscopes.

The survey methods described above can show the presence of large geologic anomalies such as anticlines (arch-shaped folds in subterranean layers of rock), fault blocks (sections of rock layers separated by a fracture or break), and salt domes, even though there may not be surface indications of their presence.

"Until that time we'd been looking down microscopes at thin sections of rock, looking at faults and outcrops on land.

In this study, we used classic structural geological fieldwork, including mechanical rock property measurements, and optical microscopy, which included image analysis of selected thin sections of rock samples.

We also prepared thin sections of rock samples of the slip zones oriented perpendicular to the fault surface and parallel to the fault striations for Raman spectroscopic analysis.

Important geological skills include petrology (to understand the depth at which crystals start to form in magma, changing its flow properties), optical mineralogy (to determine composition from thin sections of rock), and sedimentology (to understand historical deposits from volcanoes).
