In dikes and sills.
If you mean an intrusion via magma/lava, then fossils would not exist due to the fact that most fossils are found in SEDIMENTARY rock, not IGNEOUS (magma/lava rocks).
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
An igneous intrusion that forms between two layers of sedimentary rock is known as a "sill." Sills occur when molten magma intrudes horizontally between existing rock layers, solidifying into igneous rock as it cools. This process can create distinctive geological features and may alter the surrounding sedimentary layers through heat and pressure. Sills often exhibit a uniform thickness and can vary in composition, depending on the magma source.
The sedimentary rock melts,which causes magma. When the magma cools it becomes an igneous rock.
A laccolith is a type of igneous rock formation that is created when magma intrudes between layers of sedimentary rock, causing the overlying layers to arch upward. It is classified as an intrusive igneous rock.
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.
A laccolith is an igneous formation between two sedimentary layers
No. Igneous rock forms from the cooling of magma.
igneous rock.
Sedimentary rock can change intometamorphic rock or into igneous rock. Metamorphic rockcan change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals.
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Basically, igneous intrusion involves the solidifying of magma when it cools in the crust of the Earth. When magma rises through the crust, it intrudes into the existing sedimentary rock layers and forms a hill. The surounding rock may be more prone to erosion and wear away leaving the intrusion jutting above the (eroded) surroundings.
