Dynamic recrystallization mechanisms and vorticity estimation of the Terrane Boundary Shear Zone (Lakhna shear zone): Implications on dynamics of juxtaposition of the Eastern Ghats Mobile Belt with the Bastar Craton, NW Odisha

Abstract: The Terrane Boundary Shear Zones provide important information regarding tectonics of juxtaposition between different terranes. In this paper, we have studied the Lakhna shear zone, between the Eastern Ghats Mobile Belt and the Bastar Craton. Detailed structural study, sampling and strain analysis through measurement of size and orientation of dynamically recrystallized quartz grains indicate: (i) the Lakhna shear zone is developed on granitic protolith of the Bastar Craton, (ii) mylonites are quartzofeldspathic in composition, marked by SE dipping mylonitic foliation and down dip stretching lineation defined by biotite and quartz grains, (iii) S-C fabric and rotated porphyroclasts indicate a NW vergence thrust kinematics, (iv) recrystallization of quartz grains occurred by climb-assisted dislocation creep through BLG near craton boundary, SGR in the central part of the shear zone, GBM towards the Eastern Ghats margin, (v) temperature of deformation increases towards mobile belt (380–560°C) that suggests thrusting of granulitic hot slab over cold craton and (vi) Wm estimates of 0.9 suggest simple shear deformation. The juxtaposition between the EGMB and the Bastar Craton occurred by simple shear thrusting when the granulitic slab was hot enough to create a difference in temperature and mechanism of dynamic recrystallization across the shear zone.

Recent developments in biocatalysis and its influence on the pharmaceutical industry

Abstract: Biocatalysis has demonstrated to be more sustainable, and the most economical, efficient, and eco-friendly process in the production of active pharmaceutical intermediates (APIs) and pharmaceuticals. Recent developments in biocatalytic reactions are driven by the advances in biochemistry, recombinant DNA technology, enzyme engineering, bioinformatics, random and site-directed mutagenesis, enzyme-directed evolution, high-throughput enzyme screening and analysis, fermentation, and robotic-artificial intelligence technologies. Biocatalysis is one of the most promising technologies, but it needs more innovation for the sustainable synthesis of advanced novel active pharmaceuticals and APIs for the future pharmaceutical. This chapter highlights the history of biocatalysis and recent developments in the production of advanced therapeutic drugs in the pharmaceutical industry.
