[1] The Permian geological context of Mallorca is part of the larger framework of the Balearic Islands, an extension of the Betic fold and thrust belt formed during the Alpine orogeny.

The base of the Permian succession is faulted against underlying Carboniferous rocks, and the transition to the overlying Lower Triassic Punta Roja Formation is marked by an unconformity.

[1] The Port des Canonge Formation represents an intra-continental fine-grained meandering river system with extensive floodplain deposits, flowing southeast along the basin's main axis.

Lutites are characterized by massive and laminated facies, disrupted by plant roots and invertebrate burrows, recording periods of low sedimentation or subaerial exposure.

[1] Palaeosols with carbonate nodules, calcrete hardpans, and gleyed patches developed under dry conditions, pointing to seasonal desiccation of ponds, which likely functioned as waterholes.

[1] A year later, however, Matamales-Andreu et al. proposed (with some doubts) that the age of the upper part of the Port des Canonge Formation could also reach the base of the middle Permian (lower Roadian).
