Is some of the body that collided with Earth to form the Moon still recognisable inside our planet?

" Scientists have dated the birth of the Solar System to about 4.57 billion years ago. About 60 million years later a “giant impact” collision between the infant Earth and a Mars-sized body called Theia created the Moon.

Now, new research suggests that the remains of the large object that collided with the young Earth to form the Moon are still identifiable deep within the planet as two large lumps. These lumps make up about 8% of the volume of the Earth’s mantle, which is the rocky zone between the Earth’s iron core and its crust."

This patient was consuming a diet high in saturated fats, including red meats, eggs, and coconut oil. 2   A behavioral modification approach was appropriate because she had multiple areas for improvement in her diet and no history of diabetes, cardiovascular disease, or hypertension. However, this conservative approach may not be appropriate for patients with cardiovascular risk factors and/or genetic hypercholesterolemia. This nutritional approach is especial...
