Determination of zeolite-group mineral compositions by electron probe microanalysis (EPMA)
A new protocol for the quantitative determination of zeolite group mineral compositions by electron probe microanalysis (EPMA, wavelength dispersive spectrometry) under ambient conditions, is presented. The method overcomes the most serious challenges for this mineral group, including new confidence in the fundamentally important Si-Al ratio. Development tests were undertaken on...Campbell, L S ; Charnock, J ; Dyer, S ; Hillier, S ; Chenery, Simon …

Influence of lithology on hillslope morphology and response to tectonic forcing in the Sierra Nevada of California
[1] Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology may influence the efficacy of soil production and sediment transport on hillslopes. We performed quantitative analysis of LiDAR digital...Hurst, Hurst, Martin D ; Mudd, Simon M. ; Yoo, Kyungsoo ; Attal, Mikael ; Walcott, Rachel

Far-field deformation resulting from rheologic differences interacting with tectonic stresses: an example from the Pacific/Australian plate boundary in Southern New Zealand
The Miocene in Southern New Zealand was dominated by strike-slip tectonics. Stratigraphic evidence from this time attests to two zones of subsidence in the south: (a) a middle Cenozoic pull-apart basin and (b) a regionally extensive subsiding lake complex, which developed east and distal to the developing plate boundary structure....Upton, Phaedra ; Craw, Dave ; Walcott, Rachel
