The Cambrian Explosion: macroevolution and biomineralization by Mark A. S. McMenamin

“…Recent advances in our understanding of the Cambrian evolutionary diversification event (Cambrian Explosion) show that, although eumetazoan stem taxa were present in the late Proterozoic, a tremendous burst of macroevolutionary change occurred near the beginning of the Cambrian. …”

REE AND Th MINERALS IN THE METASANDSTONES OF THE UDOKAN BASIN (RUSSIA) by E.V. Belogub, K.A. Novoselov, V.V. Shilovskikh, I.A. Blinov, E.E. Palenova

“…Based on ICP-MS, optical and electron microscopy, and electron back-scatter diffraction data, the paper considers the distribution and the mode of occurrence of REEs and Th in metasandstones of the Lower Proterozoic Sakukan Formation, which host mineralization of the Udokan and Unkur copper sandstone deposits. …”

Terminated Main Himalayan Thrust, evidence of Pre-Siwalik Tertiary rocks beneath and evolution of NW Himalayan foreland basin by Madhab Biswas, Kalachand Sain

“…The model also elucidates how the Pre-Siwalik Tertiary formations went down beneath the MHT and Late Proterozoic rock came out of the Indian plate to constitute the DC, BT and MWT.…”

A review of the stratigraphic characteristics and age data of the main rock units in the Bor Metallogenic Zone (Timok Magmatic Complex) by Banješević M.

“…The TMC extends on a continental crust composed of different types of the Proterozoic to the Lower Cretaceous units and consists of the volcanic/magmatic, volcanogenic-sedimentary and sedimentary rock packages. …”

New U-Pb zircon data for Maarianvaara granite and Tohmajärvi volcanic complex, eastern Finland: geologic implications by Asko Kontinen, Jarmo Kohonen, Perttu Mikkola, Matti Kurhila

“…The ca. 1.85 Ga age of the largely undeformed Maarianvaara granite, which cuts the Proterozoic protomylonitic foliation in the Archean basement gneisses, sets a minimum age for the basement-involved thrusting in North Karelia. …”

The first application of Re–Os dating on Paleoproterozoic Francevillian sediments (Gabon) by Ikouanga, Julie Ngwal’ghoubou, Reisberg, Laurie, Pierson-Wickmann, Anne-Catherine, El Khoury, Anna, Fontaine, Claude, El Albani, Abderrazak

“…Nevertheless, dating Proterozoic formations is a real challenge because they are often impacted by tectonic, magmatic or metamorphic phenomena. …”

The Borrachudos Granitic Suite: Paleo- to Mesoproterozoic A-type Magmatism in the Southeastern São Francisco Craton (SE Brazil) by IVO ANTONIO DUSSIN, MARIO LUIZ S.C. CHAVES, TANIA MARA DUSSIN, PHILLIPPE ROSSI, JACQUES CHARVET

“…The suite has ENd(T) values of -10.10 and -6.17, with TDM of 2.6-3.0 Ga, and initial 87Sr/86Sr ratio of 0.7057, indicating features of alkaline and anorogenic (A-type) within plate granitic magmas, derived from a Proterozoic crustal source. Therefore, we argue that an orogenic model for this magmatism is not viable. …”

Estimating the Geoelectric Field and Electric Power Transmission Line Voltage During a Geomagnetic Storm in Alberta, Canada Using Measured Magnetotelluric Impedance Data: The Influ... by Darcy Cordell, Martyn J. Unsworth, Benjamin Lee, Cedar Hanneson, David K. Milling, Ian R. Mann

“…As shown with forward modeling tests, the polarization is due to a feature in the lower crust (20–30 km depth) called the Southern Alberta British Columbia conductor that is associated with a Proterozoic tectonic suture zone. This forms an important link between ancient tectonic processes and modern‐day geoelectric hazards that cannot be modeled with a 1‐D analysis.…”

Devonian–Mississippian magmatism related to extensional collapse in Svalbard: implications for radiating dyke swarms [version 1; peer review: 2 approved] by Gillian R. Foulger, Sebastian Tappe, Jean-Baptiste P. Koehl, Ingrid M. Anell

“…These intrusions may be part of the Kola–Dnieper Large Igneous Province and intruded parallel to preexisting, Proterozoic–early Paleozoic orogenic structures. Their strike is inconsistent with a source from a potential mantle plume center in the eastern Barents Sea. …”

Constraints of S–Pb–Sr Isotope Compositions and Rb–Sr Isotopic Age on the Origin of the Laoyingqing Noncarbonate-Hosted Pb–Zn Deposit in the Kunyang Group, SW China by Hongsheng Gong, Runsheng Han, Peng Wu, Gang Chen, Lingjie Li

“…This deposit was first discovered in the silty and carbonaceous slate of the Middle Proterozoic Kunyang Group that is structurally controlled by thrust faults and anticlines. …”

Insights on the Permian tuff beds from the Saint-Affrique Basin (Massif Central, France): an integrated geochemical and geochronological study by Poujol, Marc, Mercuzot, Mathilde, Lopez, Michel, Bourquin, Sylvie, Bruguier, Olivier, Hallot, Erwan, Beccaletto, Laurent

“…The elemental geochemistry, the presence of inherited detrital zircons and the Hf signatures of the volcanic ones indicate the involvement of an old (Proterozoic and older) basement in the magma genesis; this crustal contribution becomes more prominent towards the top of the sedimentary succession.…”

The Middle to Late Triassic of Central Saudi Arabia with emphasis on the Jilh Formation. Part I: lithostratigraphy, facies and paleoenvironments, palaeontology and biostratigraphic... by Le Nindre, Yves-Michel, Vaslet, Denis, Vrielynck, Bruno, Krystyn, Leopold, Manivit, Jacques, Memesh, Abdullah, Davies, Roger Brett

“…The Middle to Late Triassic (Anisian–Carnian) Jilh Formation crops out along an approximately 880 km belt in Central Saudi Arabia to the east of the Proterozoic Arabian Shield. This outcrop belt has been mapped, described and analysed in detail, first by geologists of the BRGM (1990–1991) and more recently by the present authors. …”

Petrogenesis of REE-rich two-mica granite from the Indosinian Xiekeng pluton in South China Block with implications for REE metallogenesis by Defu Zhang, Defu Zhang, Tingting Lv, Xiangaung Wang, Xiangaung Wang, Mingxuan Cao, Xiquan Chen, Xiquan Chen, Yongwen Zhang, Liangxin Gong

“…Zircon εHf(t) values range from −14.93 to −9.12, with depleted mantle model ages (TDM2) of 1.86–2.03 Ga, and whole-rock Nd isotopic model ages (TDM2) are 1.90–1.93 Ga, indicating a source primarily from partial melting of Proterozoic continental crustal clay-rich mudstones. …”
