Investigation on the Height Calculation of Water Flowing Fracture Zone during Coal Mining under Ordovician Limestone Nappe Aquifer by Chengcheng Chu

“…This paper focused on the height calculation of water flowing fracture zone during mining under the Ordovician limestone nappe aquifer. According to the critical conditions of crack arresting under the action of compression-shear stress, a formula for calculating the height of water flowing fracture zone during mining under the Ordovician limestone nappe aquifer was proposed, which takes tectonic stress, the influence of fault, the mechanical effect of the seepage field on the stress field, and the rock softening with water into consideration. …”

U-Pb monazite ages from the Pakistan Himalaya record pre-Himalayan Ordovician orogeny and Permian continental breakup by Palin, R, Treloar, P, Searle, M, Wald, T, White, R, Mertz-Kraus, R

“…These ages, together with along-strike equivalent rocks in the Lesser Himalaya of India and Nepal, help to define an Ordovician orogeny (the Bhimpedian orogeny, also called the Kurgiakh orogeny) spanning at least from 490 to 460 Ma, which followed Neoproterozoic–Cambrian sedimentation and preceded Late Ordovician–Silurian postorogenic molasse deposition and development of a stable shelf margin at 460–440 Ma. …”

Cold feet: trackways and burrows in ice-marginal strata of the end-Ordovician glaciation (Table Mountain Group, South Africa) by Davies, NS, Shillito, AP, Penn-Clarke, CR

“…New observations from an outcrop of Upper Ordovician Table Mountain Group strata (Matjiesgoedkloof, Western Cape Province, South Africa) have revealed an unexpected ichnofauna that is hosted within diamictites and sandstones that were deposited by a retreating low-latitude (∼30°S) ice sheet during the Hirnantian glaciation. …”

Kinnekullea comma (Jones, 1879), a trans-Iapetus ostracod locum for the late Ordovician Dicellograptus anceps graptolite Biozone by Williams, M, Floyd, J, Miller, C, Siveter, D, Stone, P

“…The ostracod Kinnekullea comma occurs in the upper part of the Cautley Mudstone Formation (Ashgill Series) in the Cautley district of northern England, thus geographically extending the stratigraphical value of K. comma as a locum for the Dicellograptus ancepts graptolite Biozone in Ordovician shelly marine facies of Britain and Ireland. …”
