Geodetic characterization of active Katrol Hill Fault (KHF) of Central Mainland Kachchh, western India

ABSTRACT Porcine enterovirus G (EV-G) and teschovirus (PTV) generally cause asymptomatic infections. Although both viruses have been reported from various countries, they are rarely detected from India. To detect these viruses in Western India, fecal samples (n = 26) of diarrheic piglets aged below three months from private pig farms near Pune (Maharashtra) were collected. The samples were screened by reverse transcription-polymerase chain reaction using conserved enterovirus specific primers from 5′ untranslated region. For genetic characterization of detected EV-G strain, nearly complete genome, and for PTV, partial VP1 gene were sequenced. EV-G strain showed the highest identity in a VP1 gene at nucleotide (78.61%) and amino acid (88.65%) level with EV-G15, prototype strain. However, its complete genome was homologous with the nucleotide (78.38% identity) and amino acid (91.24% identity) level to Ishi-Ka2 strain (LC316832), unassigned EV-G genotype detected from Japan. The nearly complete genome of EV-G15 consisted of 7398 nucleotides excluding the poly(A) tail and has an open reading frame that encodes a 2170 amino acid polyprotein. Genetic analysis of the partial VP1 gene of teschovirus identified porcine teschovirus 4 (PTV-4) and putative PTV-17 genotype. To the best of our knowledge, this is the first report on nearly full genome characterization of EV-G15, and detection of PTV-4 and putative PTV-17 genotypes from India. Further, detection and characterization of porcine enteroviruses are needed for a comprehensive understanding of their genetic diversity and their association with symptomatic infections from other geographical regions of India.

Shale resource assessment involves a detailed characterization of organic and geomechanical parameters for better insights on the reservoir properties and classifying areas of economic yield. In order to assess the Eocene Younger Cambay Shale (YCS) Group of the Ankleshwar field, western India for feasible shale resource play, we have applied a multistage screening methodology that combines estimation of organic richness, brittleness index, and geomechanical analyses. The estimated thermal maturity (Ro) and average total organic carbon (TOC) contents are within the range of 0.8-1.0 and 1.8 wt%, respectively. These estimates are comparable to the reported core-based measurements. Brittleness index (BI) based on the mineralogical composition reveals that the YCS intervals of marine origin fall into the ‘less ductile’ to ‘brittle’ zone, whereas the elastic property based estimated BI falls into the ‘less brittle’ to ‘high brittle’ zone. We established a field relationship between BI and shale volume and also deciphered the effect of TOC content on the rock elastic properties. Pore pressure in the shales is slightly above the hydrostatic gradient (10.5-11.5 MPa/km). The estimated average fracture pressure of 18.5 MPa/km, together with the BI of moderately ductile to less brittle behavior suggests that the studied shales are capable of withstanding substantial strain while hydrofracturing for effective production. We demonstrate an expedient example to characterize a potential shale unit within a producing hydrocarbon field utilizing the drilled wells with limited or no core data.

We present a synopsis of a rare and little-known species of Distimake from Western India: a complete morphological description based on recent collections is provided, and nomenclature and typification issues are resolved. The fruit and seeds are described for the first time. With new morphological evidence and a full characterization of D. rhyncorhiza, the present study corroborates its placement in Distimake and supports its identity as a distinct species. The conservation status is assessed as Endangered but its distribution range is not yet fully documented and this assessment might be reviewed if more collections are made.
