Deformation partitioning and porphyroblast rotation in meta-morphic rocks: a radical reinterpretation

Creep: Time‐dependent brittle deformation in rocks

Kinematic evidence for cordierite porphyroblast growth in a contact aureole during progressive deformation; Shah-Kuh granitoid, NE Lut Block, Iran

The Shah-Kuh granitoid has intruded in the Triassic–Jurassic, pelitic and psammitic low-grade metamorphic rocks of the NE LutBlock, in Central Iran. Cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. Deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. Therela...

Metabolism during Embryonic and Meta- Morphic Development of Insects. By

Insects, because of their abundance and wide var ie ty in form and structure, have become more widely recognized in recent years as excellent mater ia l for the s tudy of m a n y physiological problems. Morphologists have intensively studied the developmental processes of insects, while relat ively few physiologists have investigated such phenomena as histolysis and histogenesis occurring durin...

Description of Time-dependent Deformation in Sedimentary Rocks

This paper deals with formulation of constitutive relations describing the time-dependent deformation in sedimentary rocks. In contrast to classical viscoplasticity, the creep effects are attributed here to a progressive evolution of material microstructure. First, an internal variable monitoring the degradation process is introduced followed by presentation of a general framework of chemo-plas...

Thin‐skinned deformation of sedimentary rocks in Valles Marineris, Mars

[1] Deformation of sedimentary rocks is widespread within Valles Marineris, characterized by both plastic and brittle deformation identified in Candor, Melas, and Ius Chasmata. We identified four deformation styles using HiRISE and CTX images: kilometer‐scale convolute folds, detached slabs, folded strata, and pull‐apart structures. Convolute folds are detached rounded slabs of material with al...
