Mesozoic mesothermal quartz‐gold‐scheelite lodes, Wakamarina, Marlborough, New Zealand [PDF]
New Zealand Journal of Geology and Geophysics, 1999 Abstract In the Wakamarina valley, Marlborough, ribbon‐banded quartz lodes fill tensional faults in Caples Terrane‐derived, Marlborough Schist and Wakamarina Quartzite. The largest of the lodes, the Golden Bar, has a strike length of at least 1.8 km and an average width of 2 m.

An Ancient Divide in a Contiguous Rainforest: Endemic Earthworms in the Australian Wet Tropics. [PDF]
PLoS ONE, 2015 Understanding the factors that shape current species diversity is a fundamental aim of ecology and evolutionary biology. The Australian Wet Tropics (AWT) are a system in which much is known about how the rainforests and the rainforest-dependent organisms

PROGNOSTIC ESTIMATE OF NOBLEMETAL RESOURCES IN PROMISING ORE DISTRICTS OF THE KARELIAN REGION
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017 The gold and platinoid resources of the Karelian region are expected to increase. Our prediction is based on the leading genetic types of noble-metal mineralization known in the region such as the low-sulphide Pt-Pd type in layered plutons and gabbro ...

Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]
, 2004 Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...
