Definition of carbonaceous in English: carbonaceousadjective ˌkɑːbəˈneɪʃəsˌkɑrbəˈneɪʃəs (chiefly of rocks or sediments) consisting of or containing carbon or its compounds. （主要指岩石，沉积物）由碳（或碳化合物）组成的；含碳（或碳化合物）的 Example sentencesExamples - The distinguishing feature of the lowermost sequence is the presence of coal or carbonaceous shale within alluvial and lacustrine strata.
- Cross-bedding, channel-fill structures, red colouration, carbonaceous material, desiccation cracks and raindrop pits indicate that these rocks were deposited in a terrestrial environment.
- Some beds contain carbonaceous fragments, and the remains of large roots are found underlying thick coal beds.
- It was intruded into a succession of thinly bedded sandstones and carbonaceous silt and mudstones.
- These microfossils, found in bedded carbonaceous cherts, are estimated to be between 3.3 billion to 3.5 billion years old.
- Similarly, there exists the potential for finding ancient samples from Mars or even Venus, as well as unweathered carbonaceous chondrites.
- This facies commonly occurs associated with carbonaceous shale and laminated sandstone.
- An additional sulphide-facies type was described as consisting of pyritic carbonaceous shale.
- Sediments at Rick Forester are light gray carbonaceous sandy clays.
- An exception may be its type locality in Colombia, where it occurs in veinlets and pockets in carbonaceous sedimentary units apparently distant from igneous rocks.
- In Proterozoic carbonaceous fossils, ultrastructural and biochemical characters are unavailable, and anatomical and reproductive structures are uncommon.
- The association of the cherts with carbonaceous sandstones and lacustrine shales in the Rhynie Cherts Unit indicates sinter deposition interrupted alluvial floodplain sedimentation of mud and sand.
- This structure is very similar to kerogens found in carbonaceous meteorites.
- Silicified carbonaceous schist and graphitic quartzite occur as lenses or layers with extremely variable thickness and are mostly confined to the immediate vicinity of ultramafic rock units.
- The apparent increase of carbonaceous macrofossils through the Proterozoic Eon is likely a result of combined biological and environmental evolution.
- The Anna Shale was then slowly deposited under restricted marine conditions; it is highly carbonaceous and contains vascular plant fragments.
- Other fossil seed, leaf, beetle, ostracod, snail and fish remains come from a carbonaceous siltstone that represents a local waterlogged habitat.
- It is overlain by the lower shale member, which consists of interbedded carbonaceous shale and lignite that accumulated in coastal marsh and swamps landward of the shoreline.
- Based on meteorite studies, astronomers recognize that NEAs have diverse compositions, including silicate, carbonaceous and hydrocarbon-bearing, metallic, and ice-bearing materials.
- Australian coals and associated carbonaceous sediments may thus well be oil source rocks in the Gippsland basin area and elsewhere in Australia.
