Additional information

This rock has outcrops along the northern border of the Dinant Synclinorium in the Sambre and Meuse valleys and their tributaries (Burnot and Marteau Formation) and within the Verviers Synclinorium in the Vesdre valley (Marteau Formation) (Bultynck and Dejonghe, 2001).

Natural color

Characterized by garish hues, red colors dominate whereas the grey variants (grey and light grey) are less represented.

Aged color

Components

Composed of millimetrical- to pluricentrimetrical-sized well-rounded clasts (granules and pebbles) in a dark-red (called “lie de vin”) terrigenous matrix made of quartz, lithic fragments and clay minerals. The clasts consist of grey, green and reddish sandstone and quartzite pebbles (generally varying between 4 mm and 60 mm), white pebbles derived from vein quartz, and dark green and black small pebbles composed of tourmalinite (rock that mostly consist of minute crystals of tourmaline and quartz). Tourmalinite granules and pebbles are very characteristic of this material (see example central in the photograph).

Texture

poorly sorted, rounded quartz grains and clasts, millimetrical- to pluricentrimetrical-sized clasts (=> granules and pebbles)

Structure

bedding visible: coarser and finer grained lenses/laminations

Weathering

Diagnostic features

Dark green/black tourmalinite granules and pebbles are very characteristic of this material (see example of a large tourmalinite central in the photograph)
