Geology mineralogy, structure and texture of Agh-Otagh base- precious metal mineralization (North Takab) [PDF]
پترولوژی, 2017 The Agh-Otagh mineralization area in the north of Takab, was formed within the andesistic tuffaceous rocks of the Oligo- Miocene age. Mineralization include polymetallic (Cu-Pb-Zn-Au-Ag) quartz veins and silicified zones, which occurred as breccia and ...

The role of quartz during deformation of polyphase rocks [PDF]
, 2013 In this thesis, deformation mechanisms, rheology and the related microstructural evolution of quartz during deformation of polyphase rocks are investigated in natural, high temperature, small scale shear zones in granitoids. Selected shear zones are from

V. — Vein-Quartz and Sands [PDF]
Geological Magazine, 1903 Some time ago my friend Mr. Jukes-Browne asked me to examine some sand, with a view to ascertaining whether it was derived from Dartmoor. Dartmoor quartzes have so many specific characters that it is often easy to say that a quartz is not derived from that region; but owing to the fact that quartz-veins have not been studied, it is usually impossible ...

All‐Amyloid Functional Coacervates
Advanced Materials, EarlyView.This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Advanced Science, EarlyView.A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,
