A new approach to modeling perpendicular fabrics in porphyritic plutonic rocks using the finite element method
Popis výsledku v původním jazyce
A growing body of field evidence indicates that hypersolidus fabrics preserved in syntectonic plutons are likely to have formed in highly crystallized 'rigid sponge' magma. This paper demonstrates that such magma could be idealized as a rheological solidand that the development of non-coaxial fabrics in plutonic rocks can very conveniently be modeled in the framework of solid mechanics. Using the finite element method (FEM), we modeled two strain regimes of small magnitudes (plane-strain horizontal simple shear with the shear strain gamma of up to 0.30 and plane-strain pure shear of up to 15% shortening) superposed onto vertically oriented and variously spaced elastic phenocrysts set in the viscoelastic matrix. In the simple shear regime, the phenocrysts slightly rotate toward the shear plane, while the principal strain directions in the matrix are instantaneously oriented at an angle of about 45 degrees or less to the phenocryst fabric. Simple shear thus can only lead to the formatio
