Deformation control of carbonaceous schist stratigraphy of the Xinxunyang tunnel of Xiangyu line Ⅱ
Stratification of rocks into beds.
A sedimentary basin is an area of the earth's crust that is underlain by a thick sequence of sedimentary rocks.
A banded or foliated metamorphic rock, usually of the same composition as granite.
2.16 The brief target oil and gas zone are from 2300 to 2500 meters. The formation is:sand, sand-stone, shale cross.
The samples on the right side of the table look like layered rocks. are they foliated fault rocks?
The plateau sloped down, to the south, toward outcroppings of rock that gave the landscape a chaotic look
informal lithostratigraphic unit
discontinuous lithostratigraphic unit
the arrangement of leaflike layers in a rock.
(geology) a stratum of rock (especially sedimentary rock).
To lie at an angle to the horizontal plane, as a rock stratum or vein.
To form bends in(a stratum of rock.
A bend in a stratum of rock.
a relation between the fossil content of a stratum and its lithology
Stratigraphy studies the sequence of the rocks in the earth's crust.
The fault scarp in ground surface approximately is along the fault face that consists of Cretaceous sandstone and Archaean gneiss.
A shale formation with sandstone interbedded is also a potential oil bearing formation.
