Science - Geology / Rock
Spanish term or phrase: corneana
A sort of metamorphic rock:

"Roca metamorfico de grano fino o mediano y microestructura granoblastico producida por metamorfismo de contacto"

If think it could be either quartzite or hornfels, but I am not sure. The document is also translated from the Catalan, and there seems to be an alternative spelling:

"corniana"

Thanks

Hornfels (German, meaning "hornstone") is the group designation for a series of contact metamorphic rocks that have been baked and indurated by the heat of intrusive igneous masses and have been rendered massive, hard, splintery, and in some cases exceedingly tough and durable. Most hornfelses are fine-grained, and while the original rocks (such as sandstone, shale and slate, limestone and diabase) may have been more or less fissile owing to the presence of bedding or cleavage planes, this structure is effaced or rendered inoperative in the hornfels. Though they may show banding, due to bedding, etc., they break across this as readily as along it; in fact, they tend to separate into cubical fragments rather than into thin plates. The most common hornfelses (the biotite hornfelses ) are dark-brown to black with a somewhat velvety luster owing to the abundance of small crystals of shining black mica. The lime hornfelses are often white, yellow, pale-green, brown and other colors. Green and darkgreen are the prevalent tints of the hornfelses produced by the alteration of igneous rocks. Although for the most part the constituent grains are too small to be determined by the unaided eye, there are often larger crystals of garnet or andalusite scattered through the fine matrix, and these may become very prominent on the weathered faces of the rock.

Tengo que reconocer que el término español de corneana suena bastante mejor que su equivalente en inglés o alemán (Hornfels). Las corneanas son conocidas como rocas cuya apariencia puede variar ampliamente. Normalmente son bastante oscuras, incluso negras, muy duras y densas y no tienen el pulido intenso del basalto o gabro. Se consideran piedras poco llamativas.
