Resumen

Imágenes de catodoluminiscencia fría (CCL) han revelado microestructuras cataclásticas relictas en mármoles y calco-esquistos de las unidades de más alta presión del complejo de Samaná. El tamaño de grano de estas microestructuras presenta una distribución auto-similar de tipo potencial con una ruptura de pendiente en log(r_i)=1.7. La fracción de mayor tamaño (1.7<log(r_i)<2.4) presenta una dimensión fractal D₂=2.43 en las microestructuras de calcita de las muestras de la unidad de Punta Balandra y D₂=2.72 en la unidad de Santa Bárbara. Ambos valores están dentro de los valores habituales de las cataclasitas carbonatadas y tienen ajustes lineales de R²=0.95 y 0.93 respectivamente. Sin embargo, la fracción de tamaño fino (0.9<log(r_i)<1.7) se caracteriza por D₁<1, por debajo del rango fractal de las distribuciones de tamaño de grano para las fábricas cataclásticas puras, aun presentando un mejor ajuste.

Microestructuras como superficies de disolución, cantos interpenetrados y el mayor redondeamiento y menor irregularidad en los bordes de grano de la fracción fina indican que el creep de disolución-precipitación dominó tras la cataclasis. La reducción del tamaño de grano, la caída de los esfuerzos diferenciales tras el proceso cataclástico y la alta presión de fluidos, proporcionaron unas condiciones favorables para el creep de disolución-precipitación. La transición del flujo cataclástico al creep de disolución-precipitación fue escalo-dependiente y homogeneizó la fracción de grano fina. Consecuentemente, la ruptura de pendiente entre D₁ y D₂ es interpretada como un registro en la distribución de tamaños de grano producido por un cambio en el mecanismo de deformación dominante.
