Subsurface Structural and Crustal Assessment on the Basis of Gravity Data Along Bagh, Dir Kot and Adjoining Areas of Azad Jammu and Kashmir, Pakistan

The research work is based on gravity data is taken from numerous parts of an active tectonic belt of AzadKashmir to delineate the crustal thickness and demarcation of thin- skin and thick-skin structures in the study area. Thestudy area includes Bagh, Dhirkot, Arja, Kohala, Sudhan Gali, Ghazi Abad, Chikkar and Chakoti. The study areabounded by the latitude 33°59′3″ and 34°9′22″ N and longitude 73°37′26″ and 73°40′16″ E. The proposed study area isa complex geological entity and is an active zone. This study has been focused to assess the subsurface lithology andstructural geometry present in Bagh and surrounding areas. For this purpose the gravity data has been acquired with thehelp of CG-5 Auto-grav using multi-profile survey technique. Gravity model suggested that Riasi Thrust in the studyzone is plunging at an angle of 42° NE and pierces to a depth of 7 km in the sub-surface. The model also suggested thatBagh Basement Fault in the study area is dipping at an angle of 75° NE in the crystalline basement up to Moho depth.Shaheed Galli Thrust has been delineated in Dhirkot area. The fault dips at 49° NE and penetrated up to a depth of 8km in the sedimentary/meta-sedimentary wedge. The geological model demarcated, 11 km depth of sedimentary/metasedimentary wedge in the southwest and 13 km in the northeast area. The crustal thickness increases from 51 km in thesouthwest area to about 53.17 km in the northeast area.

Crack size determination using electrical potentials both in service and in the laboratory has been undertaken for many years. In the laboratory this has mainly concentrated on the measurement of crack depth, with either alternating current (AC) or direct current (DC) supplies. Some work to determine the varying depth along the width of cracks as an inspection tool of in service parts using mapping methods has been done. This has used both AC and DC utilising various models to understand the data recorded, in Alternating Current Potential Drop (ACPD) a range of frequencies have been used to give various skin depths. The resulting analyses have been grouped into two groups 'thin skin' and 'thick skin', in the thin skin case the skin depth is significantly smaller than the depth of the crack 1/10th of the crack depth whereas in the thick skin cases are for cases where skin depth is over this limit. Some work has been carried out to try and unify these two approaches. The work presented here looks to develop a method using variable frequency ACPD to resolve further information about cracks growing in laboratory specimens. A system has been developed to rapidly sweep a wide frequency band and record voltage drop across a crack or feature. A selection of steel samples with known geometries and features have been used to trial and benchmark the technique. These samples have a range of cross sections as well as machined features or a range of shapes and sizes to simulate a range of crack geometries. This work has been approximated using a 2D computational model. This has been done using a reduced thickness approach.

In the present paper, we describe the first complex multifocal noninvasive morphological and functional study that enabled us to define specific qualitative and quantitative features of neonatal skin. A complex morphofunctional examination of 10 infants aging from 1 to 28 days was performed by optical coherence tomography (OCT) device with a flexible probe at the wavelength of 920 nm with longitudinal resolution of 20 μm and transverse resolution of 25 μm with simultaneous measurement of skin functional parameters. The OCT images of neonatal thin skin have organized layered structure with four horizontally oriented layers. Thick skin of newborns has no structure typical for adult skin and no clear transition from the papillary to the cellular dermis. Thus, we show for the first time to our knowledge that neonatal thick skin differs structurally and functionally from adult skin. Structurally, it differs by a loose arrangement of stratum corneum squamae and thinner epidermis and papillary layer of dermis. The functional differences are lower transepidermal water loss, localization-dependent humidity, higher erythema level, and lower pigmentation. The principal structural differences between neonatal and adult skin show that skin structure formation is not completed by the moment of birth.
