Hi there
Could you please correct me? I think underlined part says: chondrules cooled fast, so heating events must been focused. Is it correct? explain to me, please.
A few chondrules contain grains that survived the melting event, so these enigmatic chondrules must have formed when compact masses of nebular dust were fused at high temperatures-approaching 1,700 degrees Celsius-and then cooled before these surviving grains could melt. Study of the textures of chondrules confirms that they cooled rather quickly, in times measured in minutes or hours, so the heating events that formed them must have been localized.

Thank you in advance
