1A rock formation from which later sediments are derived or in which a particular mineral originates.
〔地质〕矿源岩
Example sentencesExamples
The geometry or shape of individual grains appears to be a property inherited from the original crystals of the silicate minerals in the source rock.
The ultimate source rocks supplying both the metals and sulphur of these mineralizations remain speculative, because they are not exposed on the surface.
Comparisons with the potential source rocks of these sediments suggest little alteration during sediment transport and diagenesis.
It has been suggested that fluvial and lacustrine source rocks were locally deposited in grabens created along the transtensional edges of these rotating microcontinental blocks.
Because the quartzitic gravels and progenitor source rock are notably heterogeneous, the resultant fulgurite glass likewise is demonstrably variable, as seen by the range of colors, textures, and swirled banding.
1.1A sediment containing sufficient organic matter to be a future source of hydrocarbons.
烃源岩（生油岩）
Example sentencesExamples
The lower limit of intermediate-burial diagenetic settings, and thereby the upper limit of deep-burial diagenetic settings, is defined as the top of the liquid oil window in hydrocarbon source rocks.
The Ara Group has a high hydrocarbon potential and contains carbonate reservoirs, organic-rich carbonate and shale source rocks and evaporite seals.
This work found strong evidence for the existence of potential source rocks and reservoirs of oil and gas in Yukon Flats.
However, permeability barriers may also inhibit the migration of oil and gas from the source rock to the hydrocarbon reservoir.
