<prompt> Yakha inguqulo eyinkimbinkimbi yalesi sigwebo Imithombo eminingi iyavuma ukuthi i-hammerscale yakhiwe ngohlobo oluthile lwe-iron oxide.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yalesi sigwebo ithi Imithombo eminingi iyavuma ukuthi i-hammerscale yakhiwe ngohlobo oluthile lwe-iron oxide, kanti i-magnetite iyindlela evame ukwamukelwa, okuholela kumlingisi ophawulekayo we-hammerscale.
