Microstructures and Interlayering in Pyrophyllite from the Coastal Range of Central Chile: Evidence of a Disequilibrium Assemblage

Fuentenueva s/n, 18002 Granada, Spain (Received 5 December 2003; revised 19 April 2004) ABSTRACT: Pyrophyllite from a Triassic sedimentary formation from the Coastal Range of Chile has been investigated by transmission/analytical electron microscopy (TEM/AEM). The mineral assemblage includes pyrophyllite,muscovite,paragonite,a kaolin mineral,boehmite,rutile and hematite. The textures indicate that the protolith was a volcanoclastic rock. Petrographic evidence, chemistry,and the mineral assemblage suggest the intense leaching of the parent rock by a weathering process,before the metamorphic episode,to create the protolith for the pyrophyllite. Pyrophyllite always grows from the kaolin mineral,and both phases show close orientation relationships. The presence of parallel intergrowths of pyrophyllite and muscovite indicate that muscovite also grew from the kaolin mineral. Nevertheless,the composition of muscovite suggests that this phase must also form from another precursor,probably Al smectite. The AEM data and textural relationships between pyrophyllite and muscovite reveal the presence of two generations of muscovite and suggest that Na-rich muscovite recrystallized into a Na-free muscovite and paragonite. -

Cation Ordering and Pseudosymmetry in Layer Silicates'
I A merican M ineralogist, Volume60. pages175-187, 1975 Cation Ordering and Pseudosymmetryin Layer Silicates' S. W. BerI-nv Departmentof Geologyand Geophysics,Uniuersity of Wisconsin-Madison Madison, Wisconsin5 3706 Abstract The particular sequenceof sheetsand layers present in the structure of a layer silicate createsan ideal symmetry that is usually basedon the assumptionsof trioctahedralcompositions, no significantdistor- tion, and no cation ordering.Ordering oftetrahedral cations,asjudged by mean l-O bond lengths,has been found within the constraints of the ideal spacegroup for specimensof muscovite-3I, phengile-2M2, la-4 Cr-chlorite, and vermiculite of the 2-layer s type. Many ideal spacegroups do not allow ordering of tetrahedralcations because all tetrahedramust be equivalentby symmetry.This includesthe common lM micasand chlorites.Ordering oftetrahedral cations within subgroupsymmetries has not beensought very often, but has been reported for anandite-2Or, llb-2prochlorite, and Ia-2 donbassite. Ordering ofoctahedral cations within the ideal spacegroups is more common and has been found for muscovite-37, lepidolite-2M", clintonite-lM, fluoropolylithionite-lM,la-4 Cr-chlorite, lb-odd ripidolite, and vermiculite. Ordering in subgroup symmetries has been reported l-oranandite-2or, IIb-2 prochlorite, and llb-4 corundophilite. Ordering in local out-of-step domains has been documented by study of diffuse non-Bragg scattering for the octahedral catlons in polylithionite according to a two-dimensional pattern and for the interlayer cations in vermiculite over a three-cellsuperlattice. All dioctahedral layer silicates have ordered vacant octahedral sites, and the locations of the vacancies change the symmetry from that of the ideal spacegroup in kaolinite, dickite, nacrite, and la-2 donbassite Four new structural determinations are reported for margarite-2M,, amesile-2Hr,cronstedtite-2H", and a two-layercookeite. -

I know you are sitting on a rainbow and being pround of me. Preface and acknowledgments My curiosity started growing by encountering the construction problem in pile foundation while I was working as a geotechnical Engineer 8 years ago. My engineering background was unable to explain the occurrence of construction damage, but I knew there was a better solution than pouring more and more concrete into the foundation: it is finding the solution by seeing problem through scientific and engineering aspects. Therefore, I left my engineer position and started the journey of completing my Geo-scientific knowledge. Time was too fast to rewind the life after it – warming up for living abroad through working holiday at Australia, learning Geomaterials and Geosciences through International Master of Advanced Clay Science (IMACS), seeing the world through traveling and living in foreign countries, and being tough through finding my own strength. There was nothing easy, but these experiences fertilized me to have hands-on competence for completing the PhD in Geotechnical engineering. -
