igneous rock igneous rock structural features: the structure of an igneous rock is normally taken to comprise the mutual relationships of mineral or mineral-glass aggregates that have contrasting textures, along with layering, fractures, and other larger-scale features that transect or bound such aggregates. structure often can be described only in relation to masses of rock larger than a

jun 24, 2009 the textural and chemical features of the reaction products and the observed coupling between cation and oxygen isotope exchange are consistent with the results of similar experiments on the replacement of albite by k-feldspar, performed by labotka et al. and by niedermeier et al.
