A discordant igneous rock body cuts across the pre-exiting rock bed. Laccoliths and sills are examples of concordant igneous rock bodies. A laccolith is a dome shaped intrusive body that has intruded between layers of sedimentary rock. The rising magma forces the overlying layers to rise up into a dome .Click to see full answer. In this regard, what is the difference between an igneous sill and a lava flow?Sills can be confused with solidified lava flows; however, there are several differences between them. On both contact surfaces of the country rock into which the sill has intruded, evidence of heating will be observed (contact metamorphism). Lava flows will show this evidence only on the lower side of the flow.Also, which of the following is a concordant intrusive body? Glossary concordant pluton Intrusive igneous body whose boundaries parallel the layering in the country rock.

What is an intrusive igneous body?A body of intrusive igneous rock which crystallizes from magma cooling underneath the surface of the Earth is called a pluton.
