85 The physiography of the area is dominated by glaciated landforms carved in gneiss of the Fiordland Complex. The gneiss is generally dioritic, with gradations to quartzo-feldspathic and amphibolitic varieties, and is cut by mainly barren pegmatite veins; epidote is abundant. The rocks commonly show signs of post-consolidational shearing and crushing. There is a well defined zone of strongly c...

We present a tool called Gneiss that extends the familiar spreadsheet model to support creating data-drive web applications that use data from the Internet. Gneiss allows the user to extract data from arbitrary REST web services to a spreadsheet and send spreadsheet data to web services dynamically without writing conventional code. It provides new spreadsheet functions and interface elements t...

Precambrian quartzo-feldspathic gneiss was encountered at an elevation of —3616 feet in the Herman 1A well drilled in southeastern Erie County, Ohio, by the Amerada Petroleum Corporation. The five samples of this gneiss that were studied exhibit varying degrees of gneissose foliation. In order of decreasing abundance, microcline, plagioclase, quartz, and biotite together account for an average ...

In the Santander Massif of Eastern Cordillera Colombia, intense Pliocene to Holocene sulfide-rich gold mineralization occurs in a six kilometers long section La Baja fault zone, where it crosses partially migmatized gneisses and intrusions Triassic-Cretaceous quartz monzonites granites. These intrusives are mineralogically texturally similar neosome migmatites that they intrude. The as medium l...

An eclogite and its surrounding gneiss from the Malpica-Tuy zone, northwestern Spain, were studied. The eclogite contains besides garnet and omphacite, barroisitic amphibole, quartz, phengite with Si contents between 3.27 and 3.45 per formula unit (pfu), rutile, and accessory phases such as talc and (clino)zoisite-epidote. Garnet exhibits a chemical zonation with Alm59Prp13Grs24Sps4, Alm57Prp13...

Sir,?There is an impression amongst the visitors to Parjeeling that the water supplies contain mica, and is sometimes suggested that mica in the drinking Water causes irritation of the intestinal mucosa, with resultant diarrhoea. The water supply of Darjeeling is obtained from a number of perennial springs on the western slope of the Senchal range. The springs connect with a closed concrete con...

In this article, we for the first time fully describe geology and petrography of iron quartzite formation, localized in Southeast Guinea Simandou mountain range. region, a meridional distribution belt banded magnetite quartzites (itabirite) Lower Proterozoic metamorphic series has been mapped. The rocks form an extended (210 km) narrow (0.4-7 complex synclinal structure background Archean grani...
