Isotopic systematics and mass transfer in amphibolite-grade mylonites
, 1990 Alleghanian-aged deformation and grain size reduction of quartzofeldspathic and mafic rocks of the Late Precambrian Ponaganset Gneiss proceeded at amphibolite grade conditions ( 600°C, 4-6 kb), and were accompanied by considerable mobility of Si, Na, K ...

Electric signal emissions during repeated abrupt uniaxial compressional stress steps in amphibolite from KTB drilling [PDF]
Natural Hazards and Earth System Sciences, 2007 Laboratory experiments have confirmed that the application of uniaxial stress on rock samples is accompanied by the production of weak electric currents, to which the term Pressure Stimulated Currents – PSC has been attributed. In this work the PSC

Les lichens sur serpentine et amphibolite du plateau du mont Albert, Gaspésie, Québec
, 1988 At Mount Albert, Quebec, many taxa are found exclusively on either serpentine or amphibolite contiguous formations. This exclusivity is clearly more noticeable within the saxicolous lichens than within the other groups.
