Sopwith Model II: Coal strata near Newcastle
Unlike the models of generic situations this representation of coal strata was specific to a particular surveyed location in England showing several thin, and mostly hidden, coal seams

Sopwith Model V: Dislocations of coal strata
This model shows that while very little coal may appear at ground level, coal seams (subject to faults and dislocations) can be found below the ground

Sopwith Model IV: Fallacious coal indications
This model depicts the scenario where from the surface an abundance of coal appears to exist, but there is actually very little quantity below

Sopwith Model I: Stratified rocks / denudation
Black lines in this model represent coal seams, between lighter shales and sandstones. When separated the lower section shows a gently inclined valley floor

Sopwith Model II: Coal strata nr Newcastle
Unlike the models of generic situations this representation of coal strata was specific to a particular surveyed location in England showing several thin, and mostly hidden, coal seams

The Sopwith Models take us on a journey through the fascinating world of coal seams, revealing their intricate formations and unexpected challenges. In Model II, we delve into the depths near Newcastle, where coal strata lie in wait to be discovered. The dislocations of these strata are brought to light in Model V, showcasing the complex nature of their arrangement. However, caution must be exercised as Model IV warns us about fallacious indications that may mislead even the most seasoned explorers. Amidst this exploration lies an important backdrop - stratified rocks and denudation play a crucial role in understanding coal seam formation. As emphasized by Model I, these stratified rocks provide valuable clues about the history and composition of our planet's layers while denudation exposes hidden treasures beneath. With each repetition of Models II and IV alongside multiple mentions of Model I throughout our caption, it becomes evident that coal seams hold secrets worth unraveling. From Newcastle's rich deposits to dislocated formations challenging conventional wisdom and deceptive signs leading astray – there is much more than meets the eye when it comes to these ancient carbon-rich layers. So let us embark on this scientific adventure with Sopwith Models as our guide; they illuminate both the wonders and pitfalls encountered along the way. Through diligent study and careful observation, we can unlock new insights into how coal seams shape our world while appreciating their enigmatic beauty formed over millions of years.
