natural asphalt (asphalt (bituminous material), bitumen (material), ... Materials (hierarchy name)) |
|
Note: Asphalt found in natural deposits, as distinguished from asphalt formed as a residue from the distillation of petroleum. Natural asphalt is found where crude oil seeps from the ground. It was formed during an early stage in the breakdown of organic marine deposits into petroleum. It characteristically contains minerals, while residual petroleum asphalt does not (although minerals may be added).

Additional Notes: |
|
| Dutch ..... Asfalt dat wordt aangetroffen in natuurlijke afzettingen, in tegenstelling tot asfalt dat wordt gevormd als een residu na de distillatie van petroleum. Natuurlijk asfalt ontstaat waar ruwe olie uit de grond komt. Het wordt in een vroeg stadium gevormd bij de afbraak van organische mariene afzettingen in petroleum. Het bevat meestal mineralen, in tegenstelling tot residuaal petroleumasfalt (hoewel mineralen wel kunnen worden toegevoegd). |
