Exempel på hur man kan använda CAPROCK i en mening

• Hilgard, an experienced geologist who was prospecting for oil and other minerals, conducted exploratory borings in Calcasieu Parish, Louisiana and discovered sulfur in the caprock of a salt dome.
• The city rests on a windblown deposit called the Blackwater Draw Formation, which is underlain by a thick layer of caliche, referred to locally as the "caprock".
• Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away.
• In geology and geomorphology, cuesta refers specifically to an asymmetric ridge with a long and gentle backslope called a dip slope that conforms with the dip of a resistant stratum or strata, called caprock.
• Subsequent erosion (for more than 200 million years) has preferentially removed various softer surrounding rocks, especially the easily dissolved Greenbrier limestone, leaving areas of the hard Pottsville conglomerate as a caprock protecting softer rock strata immediately beneath.
• In 1867, miners discovered sulfur in the caprock of a salt dome in Calcasieu Parish, Louisiana, but it was beneath quicksand, which prevented mining.
• The chemically resistant sediments comprising the Big Clifty, and similar siliciclastics, act as a caprock over the dissolving carbonates.
• The surface of hard, erosion-resistant rock strata forms the caprock of the backslope (dip-slope) of the homoclinal ridges from which erosion has preferentially stripped any weaker strata.
• A resistant caprock on the top of yardangs has been observed in Viking, Mars Global Surveyor, and HiRISE photos.
• A resistant caprock on the top of yardangs has been observed in Viking, Mars Global Surveyor, and HiRISE photos.
• The Shinarump Conglomerate is a highly resistant coarse-grained sandstone and pebble conglomerate (minor or major conglomerates are a typical base layer after unconformities or disconformities; the Shinarump is a major conglomerate) with rare lenses of mudstone, sometimes forming a caprock because of its hardness, cementation, and erosion resistance.
• A resistant caprock on the top of yardangs has been observed in Viking, Mars Global Surveyor, and HiRISE photos.
• The impermeable caprock is water and gastight and allows to confine high-calorie gas in the underlying fissured limestone aquifer.
• The formation is a very fine to fine red aeolian sandstone that rests on the resistant caprock calcrete of the Ogallala Formation.
• The thin, light-colored layer on top is Curtis Formation caprock, overlaying darker, reddish Entrada Sandstone, which is also the composition of the hoodoos that give Goblin Valley its name.
