No, you are missing about 70 million years. The Triassic period and Permian are between the Pennsylvanian and the Jurassic.
The igneous intrusion is typically younger than the overlying sedimentary rock layers in a dome structure. The intrusion must have occurred after the deposition of the sedimentary layers and caused them to deform and dome upward due to the force of the molten rock pushing through.
Sedimentary rock forms due to the weight of overlying sediments, which compress and cement together over time.
Pressure required for metamorphism is generated by the overlying rock layers or tectonic forces exerted on the Earth's crust. These forces cause compression, which leads to an increase in pressure within the rock, ultimately resulting in metamorphic changes. Additionally, the weight of overlying rocks contributes to the pressure required for metamorphism.
A small igneous rock body emplaced at shallow depths by uplift and arching of the overlying older strata is called a laccolith. It is characterized by a mushroom-shaped intrusion that forms when magma is injected between sedimentary strata, causing the overlying rock to arch upwards.
A glacier is formed through the accumulation of snow that compresses into ice over time. As more snow falls and compacts, it displaces air and forms glacial ice. This process is aided by the weight of the overlying snow, which causes the lower layers to compress and recrystallize into ice.

Usually weight from above, whether from a body of water or from additional sediments.

Thymus
Overlying bowel gas is more or less exactly what it sounds like - a bubble of air in the intestines that is on top of another structure you want to image with the ultrasound. Unfortunately, air bounces ultrasound waves back and doesn't allow you to see what's behind it, so you may see "overlying bowel gas" in an ultrasound report indicating the technician was unable to see some of the abdominal viscera.

The skin overlying bony prominences is the most prone to developing ulceration.
Metamorphic
Pressure required for metamorphism is generated by the overlying rock layers or tectonic forces exerted on the Earth's crust.

Additionally, the weight of overlying rocks contributes to the pressure required for metamorphism.
There is pressure within the earth due to the overlying material that the earth is formed from. The deeper within the earth you go, the greater the amount of overlying material pushing down due to gravity and so the greater the pressure. As the inner core has the largest amount of overlying material pushing down upon it, it experiences the greatest pressure.
Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
