Geology of New Eiffel

Due to the sandy and clay soil's waxy residue, some portions of the Rugbull Field could not absorb water well

The geology of New Eiffel consisted solely of sandy and clay soil which was highly problematic for agriculture. The soil did not absorb water well, resulting in flooding and puddles. The oldest rocks theorised to exist below New Eiffel were the old, hard rocks of the Palaeozoic. These consisted of Silurian mudstones and sandstones, and a Devonian strata largely of Old Red Sandstone. Above this was London Clay from the Palaeogene period. The subsoil consisted of deposits of alluvium during the Quaternary period—clay, silt, sand and gravel.

Geology

Based on geological findings of the surrounding area in London—within which New Eiffel was landlocked—the oldest rocks theorised to exist below New Eiffel were the old, hard rocks of the Palaeozoic from 538 to 251 million years ago (MYA). These consist of mudstones and sandstones from the Silurian geological period from 443 to 419 MYA, which are overlain by Devonian strata largely of Old Red Sandstone from 419 to 358 MYA. Above this is the stiff, grey-blue London Clay Formation of clay and silt; this sedimentary bedrock was formed between 56 and 47 MYA during the Palaeogene period.

Above this is the subsoil which consists of deposits of alluvium during the Quaternary period between 2.8 MYA to the present—clay, silt, sand and gravel. According to the British Geological Survey, New Leeds and most of the capital of Új Repülő consisted of sedimentary superficial deposits formed between 11,800 and 400 years ago; Plitvice and the easternmost edge of Új Repülő consisted of a sedimentary superficial deposit formed between 2.588 MYA and 400 years ago. This stratified, angular rock debris moved downslope—southerly—via the process of solifluction.

The soil was mostly sandy and clay soil, which was problematic for agriculture. Due to its waxy residue, some portions of the Rugbull Field did not absorb water well, resulting in flooding and puddles. A depression in the Field near Plitvice Bomb Shelter flooded so often that the J16 road over the area had to be diverted via a new road—the J25. In Új Repülő—atop the natural layers—are the deposits of nearly one-hundred years of human occupation, mostly consisting of lose stones. New Leeds is fully paved over.
