Regina Dass, of the Department of Microbiology, School of Life Sciences, India, also said that the Earth does not have
abiogenic or geological forces capable of producing the spore-like objects they saw on the surface.
The natural gas form Xushen-1 in Songliao Basin exhibited a heavier [[delta].sup.13][C.sup.1] value (-29.40[per thousand]) than other natural gases and was characterized by a reversed carbon isotopic distribution pattern ([[delta].sup.13][C.sup.1] > [[delta].sup.13][C.sup.2] > [[delta].sup.13][C.sup.3] > [[delta].sup.13][C.sup.4] > [[delta].sup.13][C.sup.5]), which suggested that it is an
abiogenic gas [35].
A lot of
abiogenic C[H.sub.4] is also released in the magmatic lava area [25].

Members of the family Ostreidae Rafinesque, 1815 are among the sessile marine invertebrates that live on a variety of
abiogenic and biogenic substrates (Slack-Smith, 1998; Fernandez-Leborans, 2010).
(2011) for biogenic and
abiogenic radiaxial-fibrous and fascicular optic-fibrous calcite.
Based on biogenic and
abiogenic components and texture, there are 12 microfacies in the carbonate facies, those are grouped into three depositional environments corresponding to the inner, middle and outer shelf.
Moreover, the long water residence time, thermal stability of the water column, and high
abiogenic turbidity increase the probability that dominance of filamentous cyanobacteria will occur (Scheffer, 1998), this being a characteristic environmental condition of the reservoirs in the semi-arid region of Rio Grande do Norte.
Most Precambrian chert is
abiogenic, whereas silica-secreting organisms have controlled the accumulation of most cherrty deposits since the Cambrian.
