Are occult rituals treated like spells?

Are occult rituals treated like spells? I see they can be subject to spell resistance, but can they be dispelled or blocked with spell immunity?

It’s a common belief that only those initiated in the rites and practices of arcane, divine, or psychic magic can cast spells, but this is not strictly true. Hidden within dusty libraries and amid the ramblings of lunatics lie the mysteries of another form of spellcasting—occult ritual magic. These [b]spells[\b] are rare, coveted by both those eager to gain their power and those wishing to hide their existence. Most traditional spellcasters consider these rituals dangerous and uncontrollable, something to be avoided or used as a last resort. They fear the power these ceremonies grant to the uninitiated, as the rituals allow those with only a glimmering of understanding the ability to interact with the underlying fabric of magic.

I would say yes.
