Sentence examples for at relatively shallow from inspiring English sources

Continued intrusion of magma over a period of time would cause an increase in crustal temperatures at relatively shallow depths and produce the high-temperature rocks adjacent to the high-pressure rocks generated in the subduction zone.

Most solution caves form at relatively shallow depths (from a few tens of metres to 1,000 metres) by the action of water rich in carbonic acid (H2CO3) derived from recent rainfall.

In regions with high surface heat flow, such as areas of active volcanism or mantle upwelling beneath thinned continental crust, geothermal gradients of 40 to 100 °C (104 to 212 °F) per kilometre (0.6 mile) prevail, giving rise to high temperatures at relatively shallow levels of the crust.

Traditionally, geothermal energy has been exploited in places with plentiful hot water at relatively shallow depth.

The diagram suggests emplacement of andalusite granites at relatively shallow levels in the Asbestos ophiolite, and possibly through peridotites that were already serpentinized.

In North America, the depth of rooting is usually constrained by bedrock at relatively shallow depths (less than 2 m) in many slopes [20].

Fracture bedrocks were found at relatively shallower depths of 6.7 19.5 m (av. 13.6 m) on migmatite and 5.8 m on porphyritic granite at Idere.

Methane originates from two different mechanisms: biogenic methane generation from microbial decomposition of organic matter at a relatively shallow depth; and thermogenic, which produces methane at depths of greater than 1,000 m under high temperature and pressure.

In particular, Suzuki et al. (2013) analyzed the volcanic ash erupted on 19 January, and found that it contains 8% juvenile micro-pumice in particle number, which indicates that magma must have reached at a relatively shallow level beneath the Shinmoe-dake crater at that time.

It has been argued that a high concentration of Cl- indicates an extensive water-rock interaction either at depth of a high temperature or with the granitic basement rocks at a relatively shallow depth (Edmunds et al. 1985).

It had a magnitude of 5.9 and struck at a relatively shallow depth of 6.3 miles (10km), the US Geological Survey said.
