Record number: 1, Textual support number: 1 CONT
Les phtanites sont des radiolarites graphiteuses dans lesquelles la silice a tendance à cristalliser en quartz. Il y a souvent des phénomènes d'étirement des organismes, que l'on peut observer plus rarement dans les radiolarites. En somme, on peut dire que les phtanites sont des roches siliceuses où la diagenèse tend vers un véritable métamorphisme. 4, record 1, French, - phtanite
