Chlorite polytype geothermometry

open access: yes, 1993
--Since the initial studies of chlorite polytypes, it has been suggested that the stability of the various polytypes may be a function of the temperature at which the mineral formed; however, few studies have been performed in which polytypes of chlorite

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

open access: yesSedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Investigation of U(VI) Adsorption in Quartz–Chlorite Mineral Mixtures

open access: yes, 2016
A batch and cryogenic laser-induced time-resolved luminescence spectroscopy investigation of U­(VI) adsorbed on quartz-chlorite mixtures with variable mass ratios have been performed under field-relevant uranium concentrations (5 × 10–7 M and 5 × 10–6 M)

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

open access: yesSedimentology, EarlyView.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Effects of Chlorite Alteration on Uranium Redistribution in Koongarra, Australia

open access: yes, 1990
The relevance of alteration of chlorite, one of the major constituent minerals of the host rock to uranium ore at Koongarra, to the redistribution of uranium in the vicinity of the ore deposit has been examined.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

open access: yesSedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Ni(II) sorption on natural chlorite

open access: yes, 2012
Sorption of Ni(II) onto chlorite surfaces was studied as a function of pH (5-10), ionic strength (0.01-0.5 M) and Ni concentration (10(-8)-10(-6) M) in an Ar atmosphere using batch sorption with radioactive Ni-63 as tracer.

A Regularly Interstratified Chlorite/Vermiculite in a Talc-Chlorite Vein

open access: yes
A regularly interstratified chlorite/vermiculite was found at the surface of an outcrop of talc-chlorite vein which developed in a serpentinite body at Torika, Saipi-Cho, Nagasaki Prefecture, Japan.

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, EarlyView.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.
