Wikipedia says a blackhead "is caused by excess oils that have accumulated in the sebaceous gland's duct. Blackheads are typically caused by excessive oil and makeup. While the contents inside may look dark, it is not dirt; the substance found in these bumps mostly consists of keratin and modified sebum (an oily secretion of the sebaceous gland)"
American Heritage Dictionary defines blackhead as "A plug of keratin and sebum within a hair follicle that is blackened at the surface."
American Heritage Dictionary also gives the following definitions: Keratin is "a tough, insoluble protein substance that is the chief structural constituent of hair, nails, horns, and hooves." And sebum is "the semifluid secretion of the sebaceous glands, consisting chiefly of fat, keratin, and cellular material."

It's a combination of the oils and dried skin that caused the pore to get blocked.
