Consider the following statements regarding metamorphic rocks : 1. Ortho-metamorphic rocks are formed from igneous rocks. 2. Intense heat of the intruding magmas results in metamorphism of the surrounding rocks, a process known as dynamic metamorphism. Which of the statements given above is/are correct?

Only statement 1 is correct. Ortho-metamorphic rocks are those metamorphic rocks that are derived from pre-existing igneous rocks (e.g., gneiss formed from granite), while para-metamorphic rocks are derived from sedimentary rocks. Statement 2 is incorrect because metamorphism caused by intense heat of intruding magma on surrounding rocks is called 'contact' or 'thermal metamorphism', not dynamic metamorphism. Dynamic metamorphism is caused by intense pressure due to tectonic forces (like during mountain building), not by heat from magma intrusion.
