Morphology
The meaning 'a rock consisting of coarse-grained material' is directly derivable by combining 'rudaceous' (referring to coarse rubble) with 'rock' (natural solid mineral material). This follows the standard adjective + noun compositional pattern in English, so a B1 learner who knows both constituents would understand the phrase. Although 'rudaceous' is a technical and low-frequency adjective, its contribution to meaning is literal and predictable.
Etymology
Rudaceous rock comes from a word for broken stones and paints a simple picture: a rock made of many big, rough pieces. So rudaceous means 'rubble' and the phrase means a rock made of 'coarse' or very large pieces.
